Move to pyproject.toml

[Medno]

Context

Using pyproject.toml instead of setup.py is now strongly encouraged by the Python Packaging Authority, as much of the legacy setup.py packaging interface has been deprecated.

Changes

This PR includes the following changes:

• Migrated the project configuration from setup.py to pyproject.toml.

  • Converted all supported metadata and configuration fields.
  • Removed the deprecated long_description and download_url fields.

• Removed the PyDispatcher dependency, as it does not appear to be used anywhere in the project.

• Removed the bs4 dependency, as it also does not appear to be used (from bs4 import BeautifulSoup comes from beautifulsoup library).

How to test

Build the project by running:

$> python -m pip wheel --no-deps .
