Docker container

[rsdmse]

We had a user here who needed help with the installation and encountered several issues along the way. I determined that some additional version pinnings were necessary to make the conda env work with the zeo++ python binding installation.

Our Dockerfile and image can be found at:
https://github.com/uvarc/rivanna-docker/tree/main/void/1.0.1
https://hub.docker.com/r/uvarc/void/tags

If you are interested in having the Dockerfile as part of your repo, I'll be happy to make a pull request.
