Re-instate github actions

[amorphic]

The original honestybox-measurement had various Github actions designed to do standard CI things like:

• run unit tests
• check code quality
• publish to PyPI

This card will be complete when these actions are working for netmeasure.

Test workflow is now passing for 3.8-3.11: https://github.com/amorphitec/netmeasure/actions/runs/4390016133

All actions are now working and releases are automagically published to PyPI: https://pypi.org/project/netmeasure/
