Align package structure with scientific-python template

[Alexboiboi]

This pull request restructures the package to follow the scientific-python cookie template provided by https://scientific-python.org/, updating documentation, CI/CD, and packaging configurations.

Key changes include:

• Removal of legacy README sections and addition of updated badges and warning notices.
• Modernization of CI/CD workflows (pre-commit, GitHub Actions, CD for PyPI publishing).
• Updates to the CHANGELOG and contributor guidelines to reflect the new structure.

To be covered later:

• mypy type checking
• pylint specific errors muted (check TODOs)
