Previously released as v2.0.0-beta.1 in January 2021.
A major refactor of SharePy to provide a standard [Requests auth](https://requests.readthedocs.io/en/master/user/authentication/#new-forms-of-authentication) interface.
- Converted the existing SharePoint Online authentication to a Requests auth class
- Added ADFS auth to compliment the default SharePoint Online authentication. Thanks to joemeneses
- Added automatic authentication method detection for `sharepy.connect()`
- Added version checking for saved session objects. Major version number changes invalidate a session
- Removed `auth_tld` argument from `sharepy.connect()` and replaced with an `login_url` property in auth classes
- Removed connection status messages and added Python exceptions when errors are encountered
- Fixed session files not being closed when reading and writing
- Fixed missing dependencies in PyPI package
- Added `setup.py` script to repository
