Clean up old files

[NoodlesNZ]

Trying to clean up some of the older/unused files in this project:

.gitbook/ - As far as I can see this is no longer being used
CHANGELOG.md - This is out of date and the changes are being tracked in Github releases
CODEOWNERS - The file in the root is duplicative with the one in the .github dir. I have removed the one in the root
MANIFEST.in - Used with setuptools, but not required if we're using poetry for packaging
ROADMAP.md - Out of date, we may recreate using the Github project roadmap feature
SUMMARY.md - Not sure what this is or why it was here
requirements.txt - Not required when using poetry/pyproject.toml, this is also out of date
requirements-dev.txt - Not required when using poetry/pyproject.toml, this is also out of date
setup.py - Used with setuptools, but not required if we're using poetry for packaging

I have migrated the setting from setup.py to pyproject.toml

To build and publish the package now:

Build

poetry build

Produces both a wheel (.whl) and source distribution (.tar.gz) in dist/.

Publish

poetry publish

Prompts for your PyPI username and password (or API token). To combine build and publish in one step:

poetry publish --build
