Super Mario Mash-up

Proper support for 1.21.2+. Lacks replacements for 1.21.4/.5 for the time being as they're not available yet. This is mostly out of obligation since I don't wanna make people wait that long just to avoid any loading errors that the previous version would introduce.

• This version has accurate UI going forward thanks to the introduction of the stretch_inner feature for UI sprites.
• Also added support for the Raised mod
