List of Tensors

[dxoigmn]

What does this PR do?

Right now we use tuples to signify a list of Tensors. This PR changes this to a list. Not sure this even makes sense to integrate though. This makes a lot of sense now since I forgot that the tuple could contain dicts or Tensors. Our current type annotations don't make this clear and tuple(torch.Tensor) doesn't make sense as a type annotation because it's defining the type as a tuple with a single element that is a torch.Tensor. Instead we mean that the tuple can contain many torch.Tensors.

One thing that is missing, however, is that we don't have tests for tuple/list of Tensors.
