Modernize Codebase and Enhance CI Workflow (#67)

Updated Type Hints:

Used pyupgrade with --py39-plus and --py310-plus flags to upgrade type hints to Python 3.9+ and 3.10+ syntax.
Enforced Double Quotes:

Removed skip-string-normalization = true from the black configuration in pyproject.toml.
Reran black via pre-commit hooks to enforce double quotes in the codebase.
Refactored Dependency Management:

Split requirements.txt into requirements.txt (runtime dependencies) and requirements-dev.txt (development dependencies).
Enhanced CI Workflow:

Integrated pre-commit hooks into the CI pipeline to enforce code quality checks automatically.
Added pip caching to the CI workflow to speed up dependency installation.
Automated Package Publishing:

Added a publish.yml GitHub Actions workflow to automate publishing to PyPI.
The workflow triggers on release creation or manual dispatch, builds the package, and publishes it to PyPI using twine.
