implementation inside DMN marshaller imports/uses a couple of methods from stunner, creating a dependency between the dmn marhallser and stunner itself.
Beside that, all the "converters" depends on stunner.
DNM marshaller has to be re-usable inside other editors (e.g. Scenario Simulation), and for that it must be as much lightweight as possible.
So, removal/replacement of such dependencies is needed.
The "converters" will be moved to "dmn-webapp-kogito-common"
