Define package focus

[jonringer]

It might be nice to curate a list of packages which this project is going to prioritize supporting. Currently it just says "data science", which is a large scope. It would also probably help others determine if this is a good fit for their organization.

I'd go for all packages that are used in data science and ideally upstream them to nixpkgs but expose them here.

@jonringer do you think that's too vague?
