Bm.pythagorean-triples

* First PyPI release as bm.pythagorean-triples

* Some minor additions
* consistency changes across all grscheller namespace PyPI repos

* Updated pythag3 cli script to provide more functionality
* docstring and README.md improvements

* All implementations going forward for integer_math module will use
just integer based algorithms. I can't really compete with C based
code from the Python standard library. The algorithms will then be
of use if ported to a platform without floating point arithmetic.
* added two new functions to the integer_math module
* iSqrt() finds the int square root of an int
* does same thing as math.isqrt()
* isSqr() return true if integer argument is a perfect square
* changed integer_math pythag3() function into a class method
* pythag3() -> Pythag3.triples()
* preliminary steps
* fould unrelated tweak to increase speed by 2X
* removed use of floating point numbers

* initial PyPI grscheller.boring-math release
* updated pyproject.toml to align with grscheller.datastructures

* working on pyproject.toml infrastructure for PyPI releases
* will use Flit as the packaging/publishing tool
* replaced bin/ scripts with `boring_math.integer_math_cli` entry-points
