Bootloader

Enter the bootloader in 3 ways:

Bootmagic reset: Hold down the top left key and plug in the keyboard. This will also clear EEPROM, so it is a good first step if the keyboard is misbehaving.
Physical reset button: On Blackpill board: Hold NRST and BOOT0 -> Release NRST first and quickly release BOOT0 right after.
Keycode in layout: QK_BOOT is on the second layer, replacing Escape (top left key).
