Supertokens-python

Changes
- When routing, ignores `rid` value `"anti-csrf"`: https://github.com/supertokens/supertokens-python/issues/54
- `get_redirect_uri` function added to social providers in case we set the `redirect_uri` on the backend.
- Adds optional `is_default` param to auth providers so that they can be reused with different credentials.
- Verifies ID Token sent for sign in with apple as per https://developer.apple.com/documentation/sign_in_with_apple/sign_in_with_apple_rest_api/verifying_a_user
- Removes empty awslambda folder from framework
- If json parsing fails in the frameworks, catches those exceptions and returns an empty object.

Breaking change
- Removes `sign_in_up_post` from thirdpartyemailpassword API interface and replaces it with three APIs: `email_password_sign_in_post`, `email_password_sign_up_post` and `third_party_sign_in_up_post`: https://github.com/supertokens/supertokens-node/issues/192
- Renames all "jwt" related functions in session recipe to use "access_token" instead
- jwt recipe and unit tests
- Support for FDI 1.10: Allow thirdparty `/signinup POST` API to take `authCodeResponse` XOR `code` so that it can supprt OAuth via PKCE
- Apple provider disabled for now

Changes
- all the user facing async functions now needs to be imported from asyncio sub directory. For example, importing the async implementation of create_new_session from session recipe has changed from:
python3
from supertokens_python.recipe.session import create_new_session

to:
python3
from supertokens_python.recipe.session.asyncio import create_new_session

- sync versions of the functions are now needs to be imported from syncio directory instead of the sync directory
- all the license comments now uses single line comment structure instead of multi-line comment structure

Added
- auth-react tests for flask and django
- if running django in async way, set `mode` to `asgi` in `config`

Added
- Adds OAuth development keys for Google and Github for faster recipe implementation.
- Removed the Literal from python 3.8 and added Literal from typing_extensions package. Now supertokens_python can be used with python 3.7 .

Fixes
- dependency issues for frameworks

Added
- Multiple framework support. Currently supporting Django, Flask(1.x) and Fastapi.
- BaseRequest and BaseResponse interfaces which are used inside recipe instead of previously used Response and Request from Fastapi.
- Middleware, error handlers and verify session for each framework.
- Created a wrapper for async to sync for supporting older version of python web frameworks.
- Base tests for each framework.
- New requirements in the setup file.
