Feature suggestion: `.paginated_stream/2` that mimics `Repo.stream/2`

[jtomaszewski]

We've just created a similar library ( https://github.com/allegro/ecto-cursor-based-stream ) that adds a cursor_based_stream/2 function that mimics Repo.stream function.

Just afterwards we've noticed paginator exists. Perhaps we could add a similar function here, e.g. cursor_based_stream or paginated_stream, that returns all items as stream? Would you be interested in such a code contribution? Then our library wouldn't be much needed anymore.

@jtomaszewski I think this would be a great addition to paginator.
