Example and blog use antiquated packaging techniques

Hello,

Just happened upon your blog article (it was great!) and I noticed you're using setup.py which is deprecated, the current solution should consider using pyproject.toml instead. Please update your git repo and blog to provide best practices for readers.

Cheers,

Justin

Start by locating the repository's setup.py and the referenced blog article, then review how the package is currently built and published. Update the example and blog to use pyproject.toml and current packaging best practices; done means both surfaces consistently describe the modern approach.
