 MXF muxer currently does not support muxing Prores essences.

 Here are small samples (2 frames length) from Apple Compressor, which
 hopefully help in the implementation:

 Picture coding labels observed:
 422 Proxy - Picture coding label :

 422 LT - Picture coding label :
 060e2b34.0401010d.04010202.03060200
 422 - Picture coding label :
 060e2b34.0401010d.04010202.03060300
 4444 - Picture coding label :
 060e2b34.0401010d.04010202.03060500
 4444 XQ - Picture coding label :
 060e2b34.0401010d.04010202.03060600

 I am guessing 422 HQ will then be 060e2b34.0401010d.04010202.03060400 but
 I have not yet made a sample. I can add one if requested.
