Request level singletons can not resolve fastapi/starlette Request class

When resolving request level singletons, Request class from starlette can not be resolved

As an example, editing the tests located at tests/integrations/fastapi_app/__init__.py as;

 from contextlib import contextmanager
 from typing import Iterator

-from fastapi import FastAPI
+from fastapi import FastAPI, Request

 from lagom import Container, dependency_definition
 from lagom.integrations.fast_api import FastApiIntegration

 class Inner:
-    def __init__(self, msg=None):
+    def __init__(self, request: Request, msg=None):
         self.msg = msg
+        self.request = request

The resolution gives the following error;

lagom.exceptions.UnresolvableType: Unable to construct dependency of type Inner The constructor probably has some unre
solvable dependencies

I will try to make a PR when i have time. But not promise :D
