Aethersteel Tweaks

This is a simple mod that removes the Aethersteel cave biome from the Aethersteel mod.

The biome is unpleasant to look at, blocking ore spawns from other mods and generates way too often, all of which is not desirable.

This mod uses Mixins to prevent the biome from registering.

There sadly are no configuration options, since the loading order does not allow for it.
