Set a flag to use gui or console
Currently, there are two packages - one for the console and one for the GUI. The GUI is also packed but not used into the console package - it does not save memory. So I think we should combine both and use a flag such as
Later on, if desired, we can also make a separate "console-only" package which is more lightweight.
Motivation: This would help me to use the same model file for running the scenarios (with the console) and viewing it (with the gui). Because I may have different VADERE versions in the suq-controller to re-run previous runs, with the current structure this means to have for each VADERE version a console and GUI package = double space + more organization of files
