Fixed FrozenLib's capes causing severe performance issues when switching dimensions or respawning.
Fixed NbtFileUtils creating a directory instead of a file.
Added the structure_upgrade command, only accessible in development environments.
- This takes a string for the namespace parameter, and will grab all structure pieces under the given namespace then save them to run/upgraded_structure, upgraded to the latest DataVersion.
