CLI: fix incorrect colorimetry for HD content.
Map colorimetry in common.h, not decavcodec.c
Continuation of the previous commit.
Make the colorimetry define names more consistent with industry
standard specifications and fix a few typographical errors.
There's an enum value for that after all.
Add colorimetry values as per newer H.264 and H.265 specifications.
Re-introduce some old code (plenty left to fix).
