Feature Request: Add option to disable space age

[msrd0]

I tried to use this docker image to host a factorio 2.0 game without space age. Unfortunately, the factorio server seems to always enable space age. I found this forum post which says if you remove the correct files you can disable space age: https://forums.factorio.com/viewtopic.php?t=117096

I got it working by launching the command sh -c "for mod in elevated-rails quality space-age; do rm -r /opt/factorio/data/$mod; done; /usr/local/bin/docker-entrypoint.sh factorio" for this docker image but that feels like a hack. It would be nice if there was an easier way to achieve this.
