aioredis.from_url() is missing type annotation

[guludo]

Describe the bug

The function aioredis.from_url() is not type-annotated and that causes checks with mypy --strict to fail in user code.

To Reproduce

1. Create a file (e.g. foo.py) containing the following:

   import aioredis
   redis = aioredis.from_url('redis://localhost')

2. Check that file with mypy in strict mode (e.g. mypy --strict foo.py). That will cause the following error: error: Call to untyped function "from_url" in typed context.

Expected behavior

The expected behavior is to have mypy approving the example file in strict mode.

It looks like it's a few bytes fix...
Changing

def from_url(url, **kwargs):

into

def from_url(url: str, **kwargs) -> Redis:

in the utils.py seem to do the job... in a project the only warnings were coming from this function and with the patch it's all fine.

Is there any reason for this to not be done while it looks really trivial?
