New major version 2.x

[cmars]

I open-sourced this project over 15 years ago and it shows. Python itself, the community, conventions and tooling around it have grown and evolved considerably since then. I've seen several requests which seem to be caused by this -- trying to use PySTDF in Jupyter for example.

So I'd like to modernize things a bit. That will require a new major version bump. In the process, I'd like to focus the scope of the project and improve it's quality.

Here's my plan:

Packaging

• Dependency management with poetry
• More Pythonic, adherence to standards, conventions, formatting, etc.
• JSON output formats
• Automated CI and publishing to PyPI with Github Actions
• Good test coverage with pytest, using publicly available STDF files
• A reasonable Python 3.x minimum version. Python 3.7 is about 5 years old -- that's a pretty generous support window

Focus

Drop GUI support from v2. GUI library compatibility is harder to support, it brings in dependencies that many users probably do not need or want, and it's no longer something I'm interested in spending any time on.

Instead of a GUI, I think a Pandas DataFrame integration would be useful. I might not get around to writing one, but I'd accept a contribution here.
