Cave Generator

Fixed a preset-related crash that could occur with some configurations. Original changelog below.

Additions:

• Giant stone clusters
  • In addition to adding stone layers, users can now also add giant stone clusters through their cave presets.
  • Users can add any number of clusters, each requiring the following pieces of information:
    • "state" : the blockstate,
    • "frequency" : the 0 - 1 spawn chance (to start a new cluster 1x / chunk),
    • "radius" : the radius (in blocks) -- this can be fairly high,
    • "radiusVariance" : how many blocks the radius can extend in or out for each dimension (randomly),
    • "startingHeight" : the center height, and
    • "heightVariance" : how much startingHeight can fluctuate up or down (in blocks).
  • It's worth noting that this feature is actually roughly as fast as how andesite, diorite, and granite are spawned in vanilla, if not faster.
  • Spawns after caverns are generated and before stone layers are generated.
    • All three can be used simultaneously.
• stone_clusters.json
  • A new preset to show off the feature.
• A config option
  • enableVanillaStoneClusters
    • Stops andesite, diorite, and granite from spawning in the world. Highly recommended when using the stone_clusters preset, so that the generator can replace the vanilla function instead of adding to it.
