Remove Bloat Stones

Granite, diorite, andesite and tuff no longer generate as natural stone, which leaves the rest of the terrain as it was. Nothing else in world generation is altered, so other blocks and structures still appear as usual. Mining these stones in older worlds no longer yields the bloat drops that once cluttered caves, since the mod only affects what generates. The mod runs on the server alone, and players join without installing it. Files target 1.20.1 on Fabric, with 1.0.0 as the only release, published 2024-03-23. The code is released under the CC0 1.0 Universal license, which places it in the public domain.
