Extract's mcstructures from the Bedrock leveldb (possibly saved from the /structure command) to .mcstructure files which can be moved across worlds.
python3 run.py World all - Extracts all mcstructures from the world named "World" (as seen on the in-game menu)
python3 run.py World house - Extracts the structure named "house" from the world named "World"
All extracted files will be outputted to a structures folder in the world folder.
Periods in the namespace will automatically create subdirectories in the structures folder.
Ex: destruc7i0n.test:structure will output to <world>/structures/destruc7i0n/test/structure.mcstructure
