* removed return_info, made info dict mandatory in reset
* tenatively removed deprecated seed api for environments
* added more info type checks to wrapper tests
* formatting/style compliance
* addressed some comments
* polish to address review
* fixed tests after merge, and added a test of the return_info deprecation assertion if found in reset signature
* some organization of env_checker tests, reverted a probably merge error
* added deprecation check for seed function in env
* updated docstring
* removed debug prints, tweaked test_check_seed_deprecation
* changed return_info deprecation check from assertion to warning
* fixes to vector envs, now should be correctly structured
* added some explanation and typehints for mockup depcreated return info reset function
* re-removed seed function from vector envs
* added explanation to _reset_return_info_type and changed the return statement
* Ditch most of the seeding.py and replace np_random with the numpy default_rng. Let's see if tests pass
* Updated a bunch of RNG calls from the RandomState API to Generator API
* black; didn't expect that, did ya?
* Undo a typo
* blaaack
* More typo fixes
* Fixed setting/getting state in multidiscrete spaces
* Fix typo, fix a test to work with the new sampling
* Correctly (?) pass the randomly generated seed if np_random is called with None as seed
* Convert the Discrete sample to a python int (as opposed to np.int64)
* Remove some redundant imports
* First version of the compatibility layer for old-style RNG. Mainly to trigger tests.
* Removed redundant f-strings
* Style fixes, removing unused imports
* Try to make tests pass by removing atari from the dockerfile
* Try to make tests pass by removing atari from the setup
* Try to make tests pass by removing atari from the setup
* Try to make tests pass by removing atari from the setup
* First attempt at deprecating `env.seed` and supporting `env.reset(seed=seed)` instead. Tests should hopefully pass but throw up a million warnings.
* black; didn't expect that, didya?
* Rename the reset parameter in VecEnvs back to `seed`
* Updated tests to use the new seeding method
* Removed a bunch of old `seed` calls.
Fixed a bug in AsyncVectorEnv
* Stop Discrete envs from doing part of the setup (and using the randomness) in init (as opposed to reset)
* Add explicit seed to wrappers reset
* Remove an accidental return
* Re-add some legacy functions with a warning.
* Use deprecation instead of regular warnings for the newly deprecated methods/functions
* Move tests to root with automatic PyCharm import refactoring. This will likely fail some tests
* Changed entry point for a registration test env.
* Move a stray lunar_lander test to tests/envs/...
* black
* Change the version from which importlib_metadata is replaced with importlib.metadata. Also requiring installing importlib_metadata for python 3.8 now.
