Drop: python 3.6.x

Some package dependencies need to be update (poetry) as well as the README file, pyproject.toml...

When you change pyproject.toml remember to do 'poetry lock' again and commit the poetry.lock also.

@urtzai I am archiving this project again. Every project needs some basic housework for updating dependencies to fix security issues; remove end-of-life python versions, etc. I see no activity here so for me it is just a bunch of extra notifications without value.
