Worldgen Sandbox

• This pack defines a custom dimension with a single custom biome that generates a single custom structure
• The custom structure is based on the piglin bastion, but with a custom processor that replaces some obvious blocks
• However since the vanilla structure nbt files are still being referenced in the custom structure pool, only the first prefab is being affected here
• This is because the jigsaw bloks in the vanilla structures loop back to the vanilla structure pools, not our custom structure pool
• The next step is to create custom structure nbt files with jigsaw blocks that point back to the custom structure pool, to close the loop
• It seems that these two definitions must reference an existing vanilla structure in the registry (likely to change in future versions):

• They do not need to overwrite it, however; it seems like they just use it to "group" in with that name, similar to how villages all fall under village structure type (see: /locate)
