Injecting with typing.Annotated

Hello. Thank you for building and maintaining awesome project.

FastAPI recently announced a new feature called Annotated. link Currently, dependency-injector is not compatible with this feature. How about modify it to be compatible? Like fastapi, wiring with Annotated can make several benefits like re-using, more compatibility with type checkers and so on.

See sample code following.

from typing import Annotated
from dependency_injector.containers import DeclarativeContainer
from dependency_injector.providers import Factory
from dependency_injector.wiring import inject


class Service:
    ...


class Container(DeclarativeContainer):
    service = Factory(Service)


WiredService = Annotated[Service, Provide[Container.service]]


@inject
def to_be_injected(service: WiredService):
    ...

I already made it for using at my personal work. If PR is welcome, I'll made PR with the code I've wrote and other work.
