Forked Gym server Repo

If anyone has suffered through connecting the gym to dl4j this might help them. Its a python 3.* and tensorflow 2.* compatable gym server

@cagneymoreau you are welcome to submit a PR if you want rl4j to have GYM integration.
One other community maintainer has been working on it.
Eg: https://github.com/KonduitAI/deeplearning4j/pull/514

Ok, Im playing around with them now. If I come up with something interesting Ill let you know
