Python Script to Locate Bedrock Ores in GT6

This Python script scans all chunks within the already-generated portions of your world. It outputs coordinates of ores located at Y=0 with the tile entity ID gt.MetaBlockTileEntity and an m value contained in TARGET_ORES (these will almost always be bedrock ores under normal circumstances).

Make sure you have a sufficiently new Python version (3.9 or higher) before running the script.
