General 3D Exporter

A fork of this project: https://glassblade.itch.io/isometro-exporter

But instead of exporting PNGs of the assets rendered from fixed angles, this tool is simpler and just gives you the OBJ itself while letting you preview it. The script prefix it looks for is ".geom" instead of ".bldg", other OBJs cannot be placed within the exported asset, and other IsoMetro-specific features such as "underground mode" are absent. Command line arguments passed to the tool work the same way.
