Big Globe Compat - Pyrellium

This datapack adds the nine biomes and two structures from the Pyrellium mod into the nether terrain generation for Big Globe. A few of the biomes can be kind of feature heavy, so terrain generation may be a touch slower and I'd advise pregenerating the chunks.

Additionally, for things to work as right as possible, launch the game with Pyrellium installed to generate the config file, then go into Pyrellium's config and set every option to False.
