Atlas

• the biome map is now more lenient about the colors you use

• you can now include biomes that will be conditionally loaded if their origin datapack or mod is installed (useful for when you want to use a different biome if a certain datapack is installed) (acikek)

• cave biomes and noise caves can now spawn in atlas worlds, fully configurably

• as a side effect, some of an atlas world can be generated with noise
