on Python PyPI

Upgrade the compatible version of Starlette to 0.12.0.

• This includes support for ASGI 3 (the latest version of the standard).
• It's now possible to use Starlette's StreamingResponse with iterators, like file-like objects (as those returned by open()).
• It's now possible to use the low level utility iterate_in_threadpool from starlette.concurrency (for advanced scenarios).
• PR #243.

Add OAuth2 redirect page for Swagger UI. This allows having delegated authentication in the Swagger UI docs. For this to work, you need to add {your_origin}/docs/oauth2-redirect to the allowed callbacks in your OAuth2 provider (in Auth0, Facebook, Google, etc).

• For example, during development, it could be http://localhost:8000/docs/oauth2-redirect.
• Have in mind that this callback URL is independent of whichever one is used by your frontend. You might also have another callback at https://yourdomain.com/login/callback.
• This is only to allow delegated authentication in the API docs with Swagger UI.
