This PR fixes bug #267 for voice parsing from match files of version 1.0 (the most current one) that follow the v+digit(s) pattern
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.
The unittest now contains an assertion for match voice parsing from v1.0.
