[Feature] Set Start/Stop Time for Tracks?

[Haravikk]

I'm using a few tracks where several have long lead-ins that are too quiet for what I want (combat music) and some have long silences at the end before the next track plays. For now I've had to edit down a copy to isolate only the part(s) that I want to play, which works fine but isn't ideal.

What I'd love to see is the ability to set a start and stop timestamp (defaulting to 00:00 and track length respectively) so that I can just use the files as-is and have Kenku FM skip to the part(s) that I want.
