[Feature Request] Unity MLAgents Support

[hyerra]

Motivation

Unity is a popular method for creating game environments for RL algorithms. I was wondering if potentially adding support for Unity's MLAgents framework could be considered. Here is some documentation to their low level API that could be useful for supporting Unity games:

https://github.com/Unity-Technologies/ml-agents/blob/develop/docs/Python-LLAPI.md
https://github.com/Unity-Technologies/ml-agents/blob/develop/docs/Python-LLAPI-Documentation.md

Solution

Adding direct support for Unity MLAgent environments.
