can difficulty be a filter please?

If you're referring to full game runs, Speedrun mode is functionally Advanced mode without the ability to change difficulties, so I figured it'd be best to allow difficulty to be changed in the Adventure/Quest modes and not segregate them.

If you're referencing ILs, w/ the exception of a handful of levels the difficulties don't make enough of a difference to justify a category split. Relaxed Mode already makes the current Checkpoint vs No Checkpoint split useless, and I'm considering removing the split there too.
