 I requesting new feature - yuv444p pixel format support by filter uspp

  uspp is filter from libmpcodecs, it doing full compresion/decompression
 based on snow codec,  now only support 420p/yv12 and some gray pixel
 formats (FFmpeg N-55702-g920046a), snow encoder support 444p pixel format
 - it would be nice to add that format to uspp supported formats

 -----

  I using this filter by:
  source rgb24 -> scale -> uspp -> 444p -> unsharp -> scale -> lossless
 output rgb24
  and uspp losing color information cause support only 420p
