Nether Biomes (and update to 1.14.4)

Note: Some classes also got reformatted bc the formatting seemed weirdly broken. If that was intentional you can probably just revert it after a merge.

This pr adds multiple nether biomes to the mod that can generate (aside from vanilla nether), including:

• Glowing Jungle a nether biome with less fire and dense giant mushrooms
• Condemned Barrens a biome covered in soul sand and nether cacti, with the occasional giant mushroom
• Blazing Soils similar to the nether, but with more fire and a redder netherrack variant
• Mushroom Forest like the glowing jungle but less dense and with less ground cover, and more fire. Generates as a sub biome of the vanilla nether

As I am not completely sure of how the config should be integrated with the biomes I have left that mostly to you as the mod creator.

I also tweaked how blue and green large mushrooms generate a bit so that they have more chances to be able to generate each time the generate method is called
