add "tidy note fix" option

[ma_spaghett]

so recently i just recorded my own sequence but i didn't have the "snap recorded notes to grid" option enabled (on the bottom left) since i genuinely forgot to enable that option. an option to make them snap to grid for every note would be wonderful since in my sequence there is a LOT of notes and pressing them one by one would be such a pain...


basically, please add an option to reverse humanized sequences (can't ctrl z)

This is called quantizing and would be useful
