This adds redcode (the file format of RED one, R3D) support to blender. Seems to work fine with the footage I found on the web, but keep in mind, that because of the unoptimized nature of libopenjpeg, frame decoding isn't that fast. It is also a rather challenging task, to make 4k-float-footage realtime :)

@brief Implementation of a tile coder/decoder (TCD)

The functions in TCD.C have for goal to encode or decode each tile independently from

each other. The functions in TCD.C are used by some function in J2K.C.
