Prores encoders do not support writing alpha

Description

Kostya's prores encoder currently only supports PIX_FMT_YUV444P10 as yuv444 format, meaning no alpha channel is written to the output file. See ticket #1728 for a sample with actual alpha content.

There is currently no suitable pixel format in FFmpeg, see ticket #1749 for the enhancement request.
