Trying to resolve errors with aio package #15

Hi @ColdrickSotK - I merged PR #13 and added the example you posted as the basis for a test; unfortunately there's now a large number of type errors that happen when I run it:

E     ../../home/bl/code/py/grpc-stubs/grpc-stubs/aio/_interceptori:52: error: Definition of "metadata" in base class "_ClientCallDetails" is incompatible with definition in base class "ClientCallDetails" (diff)

I think a lot of it stems from the fact that the aio module uses a bit of an unholy mix of the abc module combined with messy multiple inheritance and type overloads just for good measure.

Do you have any suggestions for how some of these issues can be resolved?
