Improve handling of image subtitle IDs in XML (DoM bug #1965)

2021-04-16T20:49:35Z

When reading/writing the XML for image subtitles, we assumed that the content of the tag is just the ID of the PNG in the MXF, without any prefix. DoM bug #1965 mentions a DCP where this is not the case, and SMPTE 429-5-2009 has an example where there is urn:uuid: in the XML. This change makes DoM write this urn:uuid: prefix, and accept it if it's present (but not complain if it's not). If the urn:uuid: _is_ required in the field, it's a bit surprising that nobody has complained up to this point. Maybe nobody noticed, or nobody reported it. Cherry-picked from 098007a1ee6a46b6ff11398f94faff5c85951da4 in master.

Add fix_empty_font_ids() to replace empty Font ids with a dummy string.
