Compose example is awful

[Lizardbutt]

Please update your compose example. It's silly to even need to manually chown an opt directory as it's against the fundamentals of linux - (It should be in Opt, but it seems like the "normal" thing to do to avoid user confusion is throw it in the working directory, EG where the docker-compose.yml exists) just path it to a local directory and you can completely skip that step.

This is in reference to the documented compose file here : https://github.com/factoriotools/factorio-docker/blob/master/docker/docker-compose.yml
