    This commit enables signalling a colour matrix index using
    cicp_matrix_coefficients_idx (ISO/IEC 23001-8 codec independent code
    It adds the following options that replace the existing colorTransform
     - colourMatrix: The coded representation according to ISO/IEC 23001-8.
     - convertPlyColourspace: Enables conversion to/from RGB using the
       indicated matrix.
    Configuration files are updated to use the new option and to
    signal the identity matrix in the case of direct GBR coding.
