External Rotation DLLs

Hey, I was poking around the codebase and noticed there's what looks like unfinished plumbing for loading external rotation DLLs. Was this a planned feature that got shelved? Or is there a reason it was left disconnected? Right now if you want a custom rotation you either PR it into the repo or fork the whole thing. Both kinda suck if you just want to iterate on your own rotation without waiting on merges or keeping a fork up to date. It'd be nice to just build a rotation as a standalone DLL, drop it in a folder, and have RSR pick it up. Especially for stuff like: - Fight-specific rotations that change every tier - Personal rotations with weird preferences nobody else wants - WIP rotations you're still testing Happy to PR this if there's interest.
