Bug Fixes

• remove unnecessary escape character for correct parsing of sharp accidentals in nakamura match files.
• don't consider the propriety doc_order for sorting notes in the matchfile_from_alignment function if it is not present. This propriety is only present in parts from musicxml scores and previously resulted in an exception for other score formats. This solves https://github.com/CPJKU/partitura/issues/326
• during matchfile parsing, voice info is now parsed as follows: If there is no voice info, all notes get assigned voice number 1. If there is only voice info for the solo voice, the non-solo voiced notes get voice 2. If multiple notes have different voices, but not every note has a voice annotated, those with voice annotation get the annotated voice number and those without voice annotation get assigned the max voice+1 voice number. Previously all notes were assigned to voice 1 if there were any None voiced note
• during matchfile parsing, all note classes are now matched correctly. Previously classes MatchSnoteTrailingScore and MatchSnoteNoPlayedNote were always marked as MatchSnoteDeletion and MatchHammerBounceNote, MatchTrailingPlayedNote, MatchTrillNote always ended up as MatchInsertionNote. This solves https://github.com/CPJKU/partitura/issues/286
• during matchfile parsing, lines which can't be parsed are removed. Before they ended up as None in the output.

New features

• We now support import from humdrum **kern, and MEI (coming soon import Musescore and Music21, export MEI).

• Ornaments now are supported.
