Merge branch 'develop' into feature/VECTO-80-convert-all-input-data-to-si-units

* develop:
  Engine-only full cycle (3950s) basically works. Open issue: initial engine state at beginning of simulation
  * extending engine model
  * additional engine-only cycle * make engine-tests work
  * renaming conversion method (VectoMath) * changing interface of IModalDataWriter back to its previous form * extending engine model
  * extending engine model, fill more result fields; * add time information to commitSimulationStep in ModalDataWriter
  adding new column to the modal output data: simulation interval [s]
  store engine power in currentState
  move engine speed into engine's state class
