Calculation of AccurateRip disc ID seems to work correctly for pure audio, mixed-mode and enhanced CDs (including "copy controlled" ones). Finally! MusicBrainz disc ID is calculated from track offsets using discid as well. When the CD TOC is read from MusicBrainz by disc ID query it is actually recalculated, but I don't think it's a big deal. It's a good consistency check anyway. Change argument names and correct one docstring in disc.id module. There seems to be a bug regarding the length of last audio track preceding a data track in enhanced CDs: get_last_lsn() method seems to include the 11400 sectors gap before the data track in the track length. And this means the MusicBrainz disc ID is not calculated correctly for enhanced CDs now... Not sure how to handle this yet.
