Add note length to SheetMusicConverter

Sheet music will now show the correct output note length for the given SheetMusic object (not necessarily correct for the original wav file).

Ignore 64th notes
Fix improper rounding for MusicXML durations
Ignore the very first rest when parsing

The very first rest in a song is just space until the song starts.

SheetMusic and Measure have size added to its API, which gets the size of its vector.
Do not add empty measures to sheet music
