How to import a new testing environment

[YYYMarshal]

Hello, I am a beginner in reinforcement learning. Recently, while reading "Learning Multi Level Hierarchies with Hindsight," I came across your PyTorch version of the code. However, I am unsure how to integrate the Ant Reactor, Ant Four Rooms, and other environments from the original text into your coding project. Can you help me with this? thank you.
