Clément Bœsch 85cb1b9b20 avcodec/proresenc_anatoliy: use a compatible bitstream version

Quoting SMPTE RDD 36:2015:
  A decoder shall abort if it encounters a bitstream with an unsupported
  bitstream_version value. If 0, the value of the chroma_format syntax
  element shall be 2 (4:2:2 sampling) and the value of the
  alpha_channel_type element shall be 0 (no encoded alpha); if 1, any
  permissible value may be used for those syntax elements.

So if we're not in 4:2:2 or if there is alpha, we are not allowed to use
version 0.
