Backport to 1.19.2

[autumnly24]

I understand that it's a lot of work to backport, but this mod is really the only good Beta Worldgen mod for modern versions. I've been working on a beta modpack for around a month now, and 1.19.2 is the only version where all the mods I need work correctly, with the exception of Modern Beta skipping that version.

I know it's been requested a few times, but if it's possible, please do consider making this backport.
