Statick-planning

This set of plugins was merged into the main [Statick] repository and Python package.
All future development will happen in that repository.

Updated

- The Statick dependency was pinned to lower than version 0.12.
- This will ensure these plugins are not installed in the same space as the main `statick` package.
Having both packages installed would cause conflicts between plugins.

Added

- Support for Python 3.12 and 3.13.
- Use of `pyproject.toml` instead of `setup.py` and `requirements.txt`.
- Supports new plugin discovery mechanism for the main Statick tool.
- Switched from yapsy to setuptools for plugin mechanism. (sscpac/statick508)

Changed

- Disabled code coverage requirements in CI for now.
- Unable to get line coverage working with new plugin mechanism.
Unit tests still work to find problems.
- Rename plugin modules so they are shorter and less redundant.

Removed

- No longer support Python 3.8.

Changed

- Run deployment actions on ubuntu-latest.
- Make setup.py and tox.ini consistent with supported versions.
- Update versions of actions to use only tags.
- Unpin sphinx dependency used when building documentation.

Removed

- Drop support for Python 3.7 due to end-of-life on 27 June 2023.
- Removed deprecated pypi package [codecov](https://github.com/codecov/codecov-python) from Tox configuration. (#74)
Discussion at: <https://community.codecov.com/t/codecov-yanked-from-pypi-all-versions/4259>.

Changed

- Updated tool plugins to match new structure introduced in sscpac/statick423.

Fixed

- Pin flake8<5 and pycodestyle<2.9.0 until <https://github.com/tholo/pytest-flake8/issues/87> is fixed.

Removed

- Drop support for Python 3.6 due to end-of-life of that distribution.
See <https://endoflife.date/python>.
To continue using Statick with Python 3.6 [pin the version](https://pip.pypa.io/en/stable/user_guide/)
used to the `0.1` tags.
An example is at the discussion at <https://github.com/sscpac/statick/discussions/376>.

Added

- Add Python 3.10 support.
- Add plugin for VAL Parser tool from King's College London.
- Switch type hints from comment style to inline style.
- Switch workflow testing from local installed Statick to
[Statick GitHub Action](https://github.com/sscpac/statick-action).

Fixed

- Use quotes for version numbers in YAML to avoid truncating trailing zeros.
- Do not fail workflow if Codecov results are not uploaded successfully.
That step is too brittle and fails intermittently.
