Grscheller.circular-array

* BUGFIX: Fixed a subtle resizing bug
* bug probably present in all previous versions
* not previously identified due to inadequate test coverage!
* debating pulling all previous PyPI releases
* improved test coverage 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

* changed circular-array from a package to just a module
* actually breaking API change
* version number should have been v0.2.0
* gave CircularArray class foldL & foldR methods

* initial PyPI grscheller.circular-array release
* migrated Circulararray class from grscheller.datastrucutes
* update docstrings to reflect current nomenclature
