I have the tests and code ported, but there are still a few things to do, but here's a question:

We're using type annotations in importlib_resources, which of course is the right decision.  But I think we still have a moratorium on typing in the stdlib.  So do we want to remove the types from importlib.resources?

Doing so could make for more work as we continue to track importlib_resource, so I'm inclined not to remove them.
