Draw perfect pressure-sensitive freehand lines. (Python port)

This is a Python port of the perfect-freehand library originally written by Steve Ruiz in TypeScript. Please reference the documentation for that library for additional usage examples, links to other implementations, and to support the original author.

When published to PyPi, the package name is "perfect-freehand" (since the "python" is redundant). The library name when importing into python code is perfect_freehand.
