Comprehensive test/deploy caller

It seems to me that it would be better to not test on many platforms with poetry install, but rather to generate a wheel on a single one and pip install it, in order to have the same dependency resolution as my users.

The idea would be to have the test workflow in the actual repositories with four jobs:

analysis:
  description: |
    basic checks
    if this does not pass, no need to do anything else

wheels:
  description: |
     package wheels for all the platforms
     upload them as an artifact

test:
  requires: [analysis, wheels]
  description: |
    download wheels, install with pip, and run the actual tests
    publish coverage

deploy:
  requires: test
  if: release
  description: |
    download all the wheels and upload to PyPI

After designing it, a template will be provided in the docs.
