Gym 0.19.0 is a large maintenance release, and the first since @jkterry1 became the maintainer. There should be no breaking changes in this release.

New features:

• Added custom datatype argument to multidiscrete space (@m-orsini)
• API compliance test added based on SB3 and PettingZoo tests (@amtamasi)
• RecordEpisodeStatics works with VectorEnv (@vwxyzjn)

Bug fixes:

• Removed unused dependencies, removed unnescesary dependency version requirements that caused installation issues on newer machines, added full requirements.txt and moved general dependencies to extras. Notably, "toy_text" is not a used extra. atari-py is now pegged to a precise working version pending the switch to ale-py (@jkterry1)

  -Removed remaining numpy depreciation warnings (@super-pirata)
• Fixes to video recording (@mahiuchun, @zlig)

• New readme and updated third party env list (@jkterry1)
• Code is now all flake8 compliant through black (@cclauss)
