[2.0] Type annotations break mypy
I tried porting an existing project to aioredis 2.0. I've got it almost working, but the type annotations that have been added are too strict (and in some cases just wrong) and break mypy. The main problem is that all the functions that take keys annotate them as `str`, when `bytes` (and I think several other types) are perfectly acceptable and are used in my code. The same applies to `register_script`.

The `min` and `max` arguments of `zrangebylex` and `zrevrangebylex` are annotated as int, but they're used for lexicographical sorting so are string-like.

Getting the type annotations right is a fair large undertaking. If there is a desire to release 2.0 soon I'd suggest deleting `py.typed` so that mypy doesn't see this package as annotated. There are annotations for redis-py in typeshed; perhaps that would be a good place to start, although I've occasionally also had issues there.
