Issues with CMAF Section A.2 colour_primaries, transfer_characteristics and matrix_coefficients check

[nicholas-fr]

Issues encountered when testing CTA WAVE test content.

The first part of the issue is that the matrix_coefficients are not found resulting in a FAIL, but the overall status is PASS (should be FAIL if any of the 3 checks fail).

The second part of the issue is that in the content tested, valid matrix_coefficients are actually present:

"spec": "CMAF",
"section": "Section A.2",
"test": "For a CMAF Track to comply with one of the media profiles in Table A.1, it SHALL conform to the colour_primaries, transfer_characteristics and matrix_coefficients values from the options listed in the table",
"messages": [
    "Valid color primaries found",
    "Valid transfer characteristics found",
    "FAIL"
],
"state": "PASS"
}

As far as I remember, the colr box parsing in the ISOSegmentValidator has been incomplete. Color Management support has greatly improved within the last couple of years, and so should the validator.
