Adds IS31FL3731 RGB Matrix Implementation (#2910)
* adds is31fl3731 rgb matrix implementation * fix build script for force pushes * allow bootloader size to be overwritten * adds planck light implementation * split led config into 2 arrays * idk * betterize register handling * update planck implementation * update planck * refine rgb interface * cleanup names, rgb matrix * start documentation * finish up docs * add effects list * clean-up merge * add RGB_MATRIX_SKIP_FRAMES * add support for at90usb1286 to bootloader options
