Merge release into main, get all latest changes, get GitHub actions updated for final round of debugging/testing.

Description

Resolves #90 and #92

New version is already updated and published (see PyPi @ https://pypi.org/project/mlfmu/).

The only thing that failed was the creation of a new release on GitHub. Created a new script now to split that out from the rest to be able to run it separately (and debug if needed).

How Has This Been Tested?

Ran the steps as now also recommended in README
