For ST 2110-20 video/raw format-specific parameters like sampling, colorimetry, etc. are are described in the SMPTE spec, and tested by the associated test_20_7x_x functions.
However for video/jxsv the spec for the equivalent format-specific parameters and JPEG XS specific ones like profile and level is not in ST 2110-22, because that spec is agnostic to the compression. Rather they are specified in RFC 9134.
We need test functions for RFC 9134!
