WIP: mesa compat
All tests pass but some features are still missing/unclear: - Mesa agents do not have a `state`, so their "metrics" don't get stored. I will probably refactor this to remove some magic in this regard. This should get rid of the `_state` dictionary and the setitem/getitem magic. - Simulation is still different from a runner. So far only Agent and Environment/Model have been updated.
