Add support for #SENOTECHANGE command (#81)
TJAPlayer3 implementation details (https://github.com/IepIweidieng/TJAPlayer3/blob/gh-pages/tja.md#senotechange): - `#SENOTECHANGE` can be placed at the start of a measure, or in the middle of the measure - It will only apply to 1 note immediately after the command - It will override any automatic Don2/Don3/Ka2 assignment (from note clusters) How it works in `tja2fumen`: - `#SENOTECHANGE` will be tracked in the TJA measure object - It will split the measure into sub-measures (similar to gogo/bpm/etc.) - It will only be applied to the first note, after which it will be overwritten - We set a `manually_set` flag to ensure that the manually-chosen value doesn't get overwritten. Fixes #69.
