Setup automated publish pipeline using CI

[jooola]

I propose to automate the publishing of a new version to pip using the CI.

I'll only need @lukecyca to setup a secret token that allow one to publish this package to pip.

This can be triggered when pushing a new tag.

@lukecyca Could you setup a PYPI_TOKEN in the repository secrets so we can publish new releases to pypi using the CI ?

Done. It is called PYPI_API_TOKEN.
