Terralith

- Desert Caves now have a rare Golden Oasis feature - this feature will generate a distinctive oasis along with plenty of gold underneath.
- You can find veins of lapis lazuli in Ice Caves now; they are mixed with blue ice and packed ice.
- Thermal Caves have extra redstone, and some will even light up the caves.
- Rich iron deposits in Dripstone Caves are now a bit less rare, but still rarer than they were originally.
- Calcite geodes in Lush Caves can no longer generate close to the surface. The geodes that don't contain emeralds are also often hollow now as well.
- The secret in the Mantle Caves has been rebalanced and should be a bit more potent now...
