should have a conda recipe

[chhotii-alex]

It seems that many in the biological computing field favor using conda over just venv/pip. However I cannot figure out how to install diversity without using pip. It's considered hazardous to use pip to install packages into a conda environment, so we shouldn't force users to do that. Apparently (why is this the messed-up state of the world argh) conda skeleton does not know what to do with a package that doesn't have a setup.py. I'm sure that, since this is a python-only package with just a few requirements, creating a conda recipe should be pretty trivial, but conda seems to be designed to take on complicated things without making simple things simple. So I'm opening this ticket rather than taking the time to learn all about conda right now.
