Create a snakemake workflow for adding new organisms across the web app

[vineetbansal]

A snakemake workflow that adds a new organism/enzyme combination to the web application would serve as documentation on the steps we currently take to do this, as well as actually be put to use in the future (both for adding new databases and/or replacing old ones).

Let's add support for something like --organism sacCer3 to the snakemake workflow if possible.

We need to make the data path consistent with config.json.
