block coordinate order in the file is y,z,x to use the same code as classic/indev levels.
in hindsight, this was a completely arbitrary decision.
the Entities and TileEntities are nbt.TAG_List objects containing TAG_Compounds.
this makes it easy to copy entities without knowing about their insides.
rotateLeft swaps the axes of the different arrays. because of this, the Width, Height, and Length
reflect the current dimensions of the schematic rather than the ones specified in the NBT structure.
