Convert schematic files from minecraft to bloxd and vice versa

Credit: Significant parts of block-jsons.js are taken from bloxd. View the unbundled code, including block-jsons.js, here.
Supported types: .bloxdschem, .schematic, .schem, .litematic
It is recommended to use beta cubical to convert .schematic files to .schem (File -> Export File -> Sponge Schematic) for more accurate conversion.
Blocks with no equivalent are being replaced with dirt.
Splitting Info:
Minecraft Schematics that exceed bloxd's maximum chunk size get split into multiple files, compressed into a single .zip file.
The X-Coordinate specified at the end each file name represents the amount of blocks the build has to be moved on the X-Axis, compared to the position of the first schematic.
The Y- and Z-Coordinates stay the same.
