Publish to pypi and then bioconda

To make software packaging easier, it helps if all of our tools are available via conda-forge or bioconda.

@joverlee mentioned that in particular fauna isn't available via conda yet.

Motivated from a discussion in docker-base:

• Build image based on conda-base? docker-base#222

As it is now, fauna's codebase and expected usage is not suitable as an installed Python distribution. It expects to be run from a source tree. I don't think we want to expend much effort here to change that.
