feat(package): fewer dependencies with fewer version pins (#95)

* feat(cli): add builtin fragile swarm solver

 - drop dependency on fragile library since we need a fixed version, and its deps are OOOOOOOOLD.

* feat(package): drop pydantic dependency

 - we aren't using it for anything (useful)

* chore: fragile relative imports 🎉

 - tests pass and CLI works and no more numpy/gym heck

* chore: fix up numpy errors and test suite

 - we can swarm with no fragile dep or numpy version pinning :)

* chore: drop unused fragile code

* chore: fix tests

* chore: drop lots more unused fragile code

* chore: drop more unused fragile code

* chore: more unused code

* chore: drop networkx requirement and autoformat code

 - had to drop history tree 😭 but it will be fine

* chore: drop data generation swarm example

* feat(ci): add cron builds and matrix testing

* chore: update codecov range for mathy repo
