Docker (Compose) support

[JaneX8]

Great work. I just want to let you know I used your win 311, win95 and win98 repos successfully in a browser using Docker and NoVNC from this repo: https://github.com/google85/qemu-docker.

I skipped the mount step and went straight on running the qemu commands from the NoVNC interface from the /isos directories. I use it from Docker Compose https://github.com/google85/qemu-docker/blob/master/docker-compose.yml.
