use poetry for dependency management and build

[dashdanw]

https://python-poetry.org/docs/

I thought it might be interesting/useful to use poetry to manage deps/builds/project info for the following reasons

• robust dependency and platform version management
• build distributions using poetry build
• separate dev dependencies from release dependencies
• automatically manages virtual environments

If not that's cool too I just thought it would be a fun thing to do, also happy to make any changes requested
