Abandoned camps in the sulfur caves

Currently abandoned camps don't generate in sulfur caves biomes. It should be able to spawn in sulfur caves at any y-level. Unlike other abandoned camps, the tent and cushion colors are always red or yellow. Sulfur or cinnabar walls generate in place of wooden fences. Polished sulfur or cinnabar replaces grass path blocks. There are more copper chests there than any other abandoned camp's biome variant.
