KubeJS aisle tool

This mod adds a single item with the following functionality:

• Right-click a block to select the first corner of the structure.

• Shift + Right-click a second block to select the opposite corner.

• Right-click in the air to copy the selected structure to your clipboard.
  The output is automatically formatted with .aisle and .where syntax.

If the structure exceeds the clipboard's size limit, the mod will instead generate a file containing the commands and copy the file path to your clipboard.

Limitations:

• The tool supports up to 26 unique block types in a structure, due to the limitations of the alphabet used by KubeJS.

• There is a performance-based limit depending on your PC specs.
  Extremely large builds (e.g., 1024×1024×256 blocks) may cause the game to freeze or crash during processing.

The largest structure successfully tested was 64×64 chunks. It took around 30 seconds to process on a mid-range system.
