Release type and Release status showing as null

[EpsiRho]

These two tags, MusicBrainzReleaseType and MusicBrainzReleaseStatus, both show as null.
My files have then tagged through MusicBrainz picard, but they are set in picard as "Release Type" and "Release Status", this might be why they don't show. If picard labels them this way TagLib should probably check there.

@EpsiRho Are you sure?

If I tag your two fields MUSICBRAINZ_ALBUMSTATUS and MUSICBRAINZ_ALBUMTYPE in Mp3tag or "Release Status" and "Release Type" in MusicBrainz Picard

I can see the content MB-AlbumStatus and MB-AlbumType in both programs and can also read this content in TaglibSharp as frame type TXXX or directly as file.tag.MusicBrainzReleaseStatus and file.tag.MusicBrainzReleaseType

It seems to work as expected.
