* CircularArray class now using Generic Type Parameter

* new epoch in development, start of 3.0 series
* now using TypeVars
* API changes
* foldL(self, f: Callable[[T, T], T]) -> T|None
* foldR(self, f: Callable[[T, T], T]) -> T|None
* foldL1(self, f: Callable[[S, T], S], initial: S) -> S
* foldR1(self, f: Callable[[T, S], S], initial: S) -> S

* BUGFIX: Fixed a subtle resizing bug
* bug probably present in all previous versions
* not previously identified due to inadequate test coverage
* test coverage improved vastly
* made some major code API changes
* upon initialization minimizing size of the CircularArray
* have some ideas on how to to improve API for resizing CircularArrays
* need to test my other 2 PyPI projects
* both use circular-array as a dependency

* docstring updates to match other grscheller PyPI repos

* first stable release
* dropped minimum Python requirement to 3.10
