Big Globe Compat - YUNG's Better Mineshafts

This datapack adds all types of YUNG's Better Mineshafts to the terrain generation for Big Globe. With how the structures generate, moving them with structure overriders can yield strange results when it comes to the entrance shaft, so I've set it up to filter out mineshafts that try to generate outside the cave layers.

This datapack used to have the types of mineshafts depend on the cave biome they spawned in, but they are now dependant on the surface biome and the vanilla mineshaft no longer spawns like the mod normally does. The Big Globe surface mineshafts still spawn.
