Rendering atari environment

[dcharrezt]

Hi, thanks for open sourcing this framework

I was trying to visualize what the agent has learned, but I could not render the atari environment.

After the GymAtariAdapter wrapper is used when I try to render the environment I get

AttributeError: 'AtariWrapper' object has no attribute 'render'

And I can not unwrap it either

'AtariWrapper' object has no attribute 'unwrapped'

I apologize if this is the intended behavior.

Hi dcharrezt,
Thanks for pointing this out! It seems we don't have a public pointer to the unwrapped environment. For now you can use AtariWrapper._environment, we'll try to fix this soon.

This actually may be as simple as making AtariWrapper inherit from acme.wrappers.base.EnvironmentWrapper, then you'll have access to the unwrapped environment via the unprotected EnvironmentWrapper.environment instead. Can anyone confirm that this doesn't have any unwanted side effects? Otherwise I'll try to look into this next week.
