This adds faster accessors to the interface. This probably only works for Gurobi 9.5+ so we should enforce that version from now on.

Let me know when you're ready for a review. Looks good so far 🙂

Yep go ahead. Still trying to figure out what to do about CI. Have to deactivate Python 3.6 if I want to test Gurobi in the CI but can't activate 3.10 because nose is broken there. Also not sure which Gurobi versions will work with those changes, so we may want to limit it to Gurobi >= 9.5.
