Actually we already do, theora, vp8, vp9 and a few others have
completely different values for most color properties, and we just
check before initializing the context or frame fields. Since iso/itu
codecs are the ones that more consistently use all the properties
everywhere it makes sense that the enum values and field values match
and imho it's simpler to use.
