Missing colr box support #35
Description
The parser doesn't appear to support parsing of the colr box (# ISO/IEC 14496-12:2022, Section 12.1.5) which leads to parsing failure when encountered. It is supported by pyisobmf: https://github.com/chemag/pyisobmff/blob/450f8549fc16c763707c1ba7c73f305700489d58/isobmff/iprp.py#L73
