Game: Fix notelocking

- Will not skip the note if `ka` was pressed right before `don` note or `don` was pressed right before `ka` note
- Will still skip the note if `don` and `ka` is pressed at the same time (within 25ms)
- Fixed `TAIKOWEBSKIN:` in imported songs crashing the game with some values
