Typing differences between Starlette and Uvicorn

[Gascognya]

uvicorn.run(app) need typing: 'ASGIApplication'
(the asgiref package)

it's difference from typing of Starlette.__call__(self, scope: Scope, receive: Receive, send: Send) -> None

SO, IDE check and display a waring, about app
uvicorn.run(app, host="127.0.0.1", port=8080)

This issue is because we haven't solved #1217.

If someone is eager, feel free to take over my PR. I don't feel like working on it any time soon.

Even if the story is different, this is fundamentally the same as #1217.

For that reason, and housekeeping, I'm closing this issue.

Thanks for reporting it @Gascognya ! :)
