Allow changing/enhancing the session object in a afterLogin callback or similar.

It would be great if we could get a callback that would let us change the session object.
In Auth0 you can do this with https://auth0.github.io/nextjs-auth0/types/handlers_callback.AfterCallbackAppRoute.html

Our usecase is fetching the user object from our own database after login and storing the user-id and org-id that we gave that user in the session, next to the ids that workos gave them. Also you could store more information you have about the user in the session instead of having to make db calls every time.

Would have to be async so you can do db calls :)
