Support reading the YCbCr Matrix header
The value is parsed and stored as an enum constant that the consumer
can read from ASS_Track. All output images are still plain RGB,
and the consumer is expected to perform its own color correction.
Supported header values: (TV|PC).(601|709|240M|FCC) and None.
If the header is missing, a special compatibility value is used
that should be treated as TV.601 if the accompanying video stream
is YCbCr and as None otherwise. If the header is present but has
an invalid/unknown value, a different special value is substituted.
