This patch series adds swscale input/output support for the packed rgb float formats.
A few of the filters also needed support the larger 96/128 bit packed pixel sizes.

I also plan to eventually add lossless unscaled conversions between the planer and packed formats.

changes since v1
* output correct alpha is src doesn't have alpha

  swscale/input: add rgbaf32 input support
  avfilter/vf_hflip: add support for packed rgb float formats
