Made render state tool render any given state

[merlerm]

Had some spare time after the rebuttal so I decided to quickly implement #82, tested it quickly and it works, but the agent doesn't really seem to use it to do anything other than render the initial state as it did before. If we want to have kind of visual planning/investigations that @yichao-liang showed in predicators we need to look into this more.

Also one small note, when testing locally this failed:

FAILED tests/oracles/obstruction2d_medium/test_approach.py::test_oracle_solves_episode - AssertionError: seed=636: not solved in 500 steps

also on main before my changes. Here on github the test is green though. @Jaraxxus-Me any clue what's happening?

Wait what? This unit test passes on my local code, the latest main branch

tests/oracles/obstruction2d_medium/test_approach.py::test_oracle_solves_episode

And I also tried this branch it also passes:
