Update Hungarian keymap and add sendstring LUT (#8220)

* Reduce PROGMEM usage for keycode map

Bit-pack the keycode bool array to gain back a small amount of flash space.
The trade-off is an increase in runtime instructions when running macros.

It does make the code a bit harder to read, as well as maintain.

For configs that use send_string() et al, it saves ~100 bytes.

* Switch to macro and common definition

Rewrite the array declarations so both the unpacked (original) and
packed LUT arrays can use the same value definitions. This is done by
defining a macro that "knows what to do".

This makes the code much easier to read and maintain.

* Fix macro typos and improve perf

Pack the bits in a more efficient order for extraction.
And also fix the copy/paste error in the macro...

* Switch fully to packed LUT

Some minor reformatting.
Compile tested all sendstring_xyz.h to make sure they were converted
properly. Also checked that an unconverted version would generate a
compile error.

* Apply whitespace suggestions from code review

 # ISP Flashing Guide
 
-If you're having trouble flashing/erasing your board, and running into cryptic error messages like any of the following:
+ISP flashing (also known as ICSP flashing) is the process of programming a microcontroller directly.  This allows you to replace the bootloader, or change the "fuses" on the controller, which control a number of hardware- and software-related functions, such as the speed of the controller, how it boots, and other options.  
+
+The main use of ISP flashing for QMK is flashing or replacing the bootloader on your AVR-based controller (Pro Micros, or V-USB chips).  
+
+?> This is only for programming AVR based boards, such as the Pro Micro or other ATmega controllers.  It is not for Arm controllers, such as the Proton C.

-You're likely going to need to ISP flash your board/device to get it working again. Luckily, this process is pretty straight-forward, provided you have any extra programmable keyboard, Pro Micro, or Teensy 2.0/Teensy 2.0++. There are also dedicated ISP flashers available for this, but most cost >$15, and it's assumed that if you are googling this error, this is the first you've heard about ISP flashing, and don't have one readily available (whereas you might have some other AVR board). __We'll be using a Teensy 2.0 or Pro Micro with Windows 10 in this guide__ - if you are comfortable doing this on another system, please consider editing this guide and contributing those instructions!   
+Or, if you see this sort of message for a Pro Micro based controller:

+
+
+You're likely going to need to ISP flash your board/device to get it working again. 
+
+## Hardware Needed
+
+You'll need one of the following to actually perform the ISP flashing (followed by the protocol they use):
+
+* [SparkFun PocketAVR](https://www.sparkfun.com/products/9825) - (USB Tiny)
+* [USBtinyISP AVR Programmer Kit](https://www.adafruit.com/product/46) - (USB Tiny)
+* [Teensy 2.0](https://www.pjrc.com/store/teensy.html) - (avrisp)
+* [Pro Micro](https://www.sparkfun.com/products/12640)  - (avrisp)
+* [Bus Pirate](https://www.adafruit.com/product/237) - (buspirate)
+
+There are other devices that can be used to ISP flash, but these are the main ones.  Also, all product links are to the official versions. You can source them elsewhere. 
+
+You'll also need something to wire your "ISP Programmer" to the device that you're programming.  Some PCBs may have ISP headers that you can use directly, but this often isn't the case, so you'll likely need to solder to the controller itself or to different switches or other components. 
+
+### The ISP Firmware 
+
+The Teensy and Pro Micro controllers will need you to flash the ISP firmware to the controllers before you can use them as an ISP programmer.  The rest of the hardware should come preprogrammed.  So, for these controllers, download the correct hex file, and flash it first. 
+
+* Teensy 2.0: [`util/teensy_2.0_ISP_B0.hex`](https://github.com/qmk/qmk_firmware/blob/master/util/teensy_2.0_ISP_B0.hex) (`B0`)
+* Pro Micro: [`util/pro_micro_ISP_B6_10.hex`](https://github.com/qmk/qmk_firmware/blob/master/util/pro_micro_ISP_B6_10.hex) (`10/B6`)
+
+Once you've flashed your controller, you won't need this hex file anymore. 
 
 ## Software Needed
 
-* [Teensy Loader](https://www.pjrc.com/teensy/loader.html) (if using a Teensy)
-* QMK Toolbox (flash as usual - be sure to select the correct MCU) or `avrdude` via [WinAVR](http://www.ladyada.net/learn/avr/setup-win.html) (for Teensy & Pro Micro)
+The QMK Toolbox can be used for most (all) of this.  
+
+However, you can grab the [Teensy Loader](https://www.pjrc.com/teensy/loader.html) to flash your Teensy 2.0 board, if you are using that. Or you can use `avrdude` (installed as part of `qmk_install.sh`), or [AVRDUDESS](https://blog.zakkemble.net/avrdudess-a-gui-for-avrdude/) (for Windows) to flash the Pro Micro, and the ISP flashing.

 If you're not sure what your board uses, look in the `rules.mk` file for the keyboard in QMK. The `MCU =` line will have the value you need. It may differ between different versions of the board.
 
-### Advanced/Production Techniques
+### Production Techniques
 
-If you'd like to flash both the bootloader **and** the regular firmware at the same time, you need to combine the files. 
+If you'd like to flash both the bootloader **and** the regular firmware at the same time, there are two options to do so.  Manually, or with the `:production` target when compiling. 
+
+To do this manually: 
 
 1. Open the original firmware .hex file in a text editor
 2. Remove the last line (which should be `:00000001FF` - this is an EOF message)
 3. Copy the entire bootloader's contents onto a new line (with no empty lines between) and paste it at the end of the original file
 4. Save it as a new file by naming it `<keyboard>_<keymap>_production.hex`
 
-It's possible to use other bootloaders here in the same way, but __you need a bootloader__, otherwise you'll have to use ISP again to write new firmware to your keyboard.
+?> It's possible to use other bootloaders here in the same way, but __you need a bootloader__, otherwise you'll have to use ISP again to write new firmware to your keyboard.
+
+To do this the easy way, you can flash the board using the `:production` target when compiling.  This compiles the firmware, then compiles the QMK DFU bootloader, and then creates a combined image.  Once this is done, you'll see three files: 
+* `<keyboard>_<keymap>.hex`
+* `<keyboard>_<keymap>_bootloader.hex`
+* `<keyboard>_<keymap>_production.hex`
+
+The QMK DFU bootloader has only really been tested on `atmega32u4` controllers (such as the AVR based Planck boards, and the Pro Micro), and hasn't been tested on other controllers.  However, it will definitely not work on V-USB controllers, such as the `atmega32a` or `atmega328p`.
+
+You can flash either the bootloader or the production firmware file. The production firmware file will take a lot longer to flash, since it's flashing a lot more data. 
+
+?> Note: You should stay with the same bootloader. If you're using DFU already, switching to QMK DFU is fine. But flashing QMK DFU onto a Pro Micro, for instance, has additional steps needed.

+#### Advanced: Changing Fuses
+
+If you're switching bootloaders, such as flashing QMK DFU on a Pro Micro, you will need to change the fuses, in additional to flashing the bootloader hex file.  This is because `caterina` (the Pro Micro bootloader) and `dfu` handle the startup routines differently, and that behavior is controlled by the fuses.  
+
+!> This is one area that it is very important to be careful, as changing fuses is one of the ways that you can permanently brick your controller.  
+
+For this, we are assuming the 5V 16MHz versions of the `atmega32u4` (such as the 5V Pro Micro).
+
+For DFU on the `atmega32u4`, these are the fuse settings that you want: 
+
+| Fuse     | Setting          |
+|----------|------------------|
+| Low      | `0x5E`           |
+| High     | `0xD9` or `0x99` |
+| Extended | `0xC3`           |
+
+The High fuse can be 0xD9 or 0x99. The difference is that 0xD9 disables JTAG, which QMK Firmware disables via software as well, while 0x99 doesn't disable JTAG. 
+
+To set this add `-U lfuse:w:0x5E:m -U hfuse:w:0xD9:m -U efuse:w:0xC3:m` to your command.  So the final command should look something like: 
+
+    avrdude -c avrisp -P COM3 -p atmega32u4 -U flash:w:main.hex:i -U lfuse:w:0x5E:m -U hfuse:w:0xD9:m -U efuse:w:0xC3:m
+
+For Caterina on the `atmega32u4`, these are the fuse settings that you want: 
+
+| Fuse     | Setting|
+|----------|--------|
+| Low      | `0xFF` |
+| High     | `0xD9` |
+| Extended | `0xC3` |
+
+To set this add `-U lfuse:w:0xFF:m -U hfuse:w:0xD8:m -U efuse:w:0xC3:m` to your command.  So the final command should look something like: 
+
+    avrdude -c avrisp -P COM3 -p atmega32u4 -U flash:w:main.hex:i -U lfuse:w:0xFF:m -U hfuse:w:0xD8:m -U efuse:w:0xC3:m
