@BattiniSandeep I pulled in your changes as part of this PR.

Some notes:

• Updated to using black: https://github.com/psf/black, over flake8.
• I kept getting some error with the 3.11 build complaining it couldn't find the module typing-extensions, so I've currently disabled the 3.11 build in the github actions. Will create a separate issue for fixing the 3.11 build.
• @BattiniSandeep , I gave you a bad comment about updating the signature of __eq__.

The signature of __eq__ should allow comparisons against other types, i.e.:

def __eq__(self, other: object) -> bool:

so object was 100% correct here from your previous commit.

• I moved the __eq__ operator up to the parent class instead of the respective subclasses, so there's only one implementation each for Option, Try, and Either, instead of separate ones for say Some and then None.
