use poetry

[rwnx]

Using a build management system like pipenv has been a real time-saver on other projects.
I've read that poetry can do pypi projects with relative ease, so i'd like to try that out here.

This will require changes to the workflow/actions as well as the tooling required in the project

I've done some thinking and i no-longer believe this is suitable for a pypi project. It might be possible but i'm not sure the usecase is there yet.
