add test cases using Python wrapper and HAWC2

There are already some tests made ready, but everything needs to be re-activated.

• re-activate the existing Python based tests
• add more Python based tests
• make sure the intended HAWC2 versions + license manager are on the CI (download dev version too)
• test that HAWC2 can load the controller successfully
• select a few very simple HAWC2 simulations that test certain controller features

Wait until @sjan has further extend Python wrapping work in the DTUcontroller2Flex branch.
