Here are the current dependencies for Batbot.

It would be great if some of the dependencies were added to optional groups (maybe a dev group that including things like sphinx, and a cli group that included things like tqdm that were useful for using batbot as a CLI but not as a library).

The impetus for this change would be to minimize the size of batbot when being used as a library, particularly by BatAI. Keeping the entire size of BatAI to under 500MB would be a boon to deployments (especially via Heroku).

I don't know for sure if the current state of Batbot would bring BatAI over the threshold (it is currently at ~450MB), but this is certainly something we'd want to explore to keep the size down.
