Packaging

Restructure for installation as a package (Addresses #87)

Description

• Implement pyproject.toml
  • dependencies derived from requirements.txt
  • adds an entry point such that pip or pipx can generate a yasb.exe
• restructure to src layout by moving contents of "src" to "src/yasb"
• refactor all directory-relative imports to module-relative imports (import core -> from . import core, for example)

Testing

I have successfully installed yasb using pip in a virtual environment (as well as with pipx as alluded to in #87). This was done on a Windows 10 machine. The program can be run by invoking "yasb.exe" (assuming it's on PATH), and still successfully attaches to komorebi, etc.

The bar can live-update from "styles.css"; however, when reloading changes to config.yaml, yasb crashes.
Keeping the PR in draft status until I fix this.

These changes are a huge improvement in the project design, please keep working on them if you have the time or contact me if you are struggling and need help with something. I think we should all give priority to what has been suggested here by @KLimit.
