compatible with OpenAI Gym Vectorized env

[SurferZergy]

Was wondering if it is possible to make it able to wrap with OpenAI's DummyVecEnv?
Seems like most of their baselines all require a vectorized env, would it be possible to wrap it?

OpenAI also requires actions space and observation space to be specific to theirs, as in either "Box" or "Discrete", pysc2 seem to offer action in lists, and observation in objects, is there a way to translate between them?

I currently don't have the resources to work on this, so I will have to rely on the community.
