flake8-pyproject

Adds support for Flake8 version 6.x. (#12)

• Adds --toml-config command-line option to specify custom configuration file. (#10, #11)

Bumped version to 1.1.0.post0.

• Makes the pyproject.toml hook available as a Flake8 plug-in. (#8)
• The regular flake8 command then works with pyproject.toml. (#5)
• As long as this package here is installed in the same Python environment.
• The code was refactored since version 1.0. It works differently, but should do the same.

• Fixes: python -m flake8p did not return exit code.
• Uses built-in tomllib module instead of external tomli package as of Python 3.11.
• Updates documentation to point out that pyproject.toml must be in current folder.

• Adds support for Flake8 5.0+.
• Drops support for Flake8 4.x. Install the previous version, 0.9.1, to use with an older Flake8. Pip will do this automatically.

• Pins Flake8 to versions 4.x or earlier.
• This is because the way Flake8 loads configuration files has been refactored in version 5.0.0.
• Adds backward support for Python 3.6, sometimes useful on Ubuntu 18.04 LTS.
