Sorry for the long delay, I just merged the branch which finishes migrating unit tests to pytest, fixed a few misc. bugs (including figuring out correct Ensembl release versions for C. Elegans).

If merging the new code with this branch is too much work I can take a stab at porting over isolated enhancements like new species.

Hi @iskandr,

I have fixed the conflict with the main branch. Could you provide some suggestion for future edit?

Hey @y9c -- I've been cleaning up the OpenVax tools and hopefully catching some of the features from your PRs in those changes. If there's anything I have missed can you open those up as new issues or smaller scoped PRs?
