Technical Debt: Consider migration to Authlib #31
Description
Description
Currently, we're using Flask-Oauthlib, which works, however it depends on a whole bunch of packages we also depend on. This normally wouldn't be an issue, but Flask-Oauthlib is deprecated and forcing us to use many older dependencies (for instance, the highest Werkzeug version we're allowed to use is 2.3.8, as Flask-Oauthlib uses some 2.x-only features. This also means the latest version of Flask we can use is 2.3.3).
The fix for this is to upgrade to Authlib, which is maintained and is the spiritual successor to Flask-Oauthlib as indicated by it's README.
