Will n-D observation states be supported?

[GreatArcStudios]

From the util function (and testing with ALE/Bowling-v5), it appears that only 1-D (vector) observation shapes are supported. Allowing for n-D shapes can be interesting as it can open up experiments things like text-embeddings, while maintaining the given structure.

Is there a plan to add this in?

Yes, we plan to implement such features in time. I am adding this to the TODO list. Thank you!
