Merge pull request #818 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:feature/VECTO-1241-engineering-mode-adding-support-for-additional-pto-activations to develop

* commit 'c8dfbdda': (26 commits)
  Updating user manual for PTO activations mode 2 and 3
  allow pto activity already at drive-off, interpolate pto power between entries in cycle
  udating project file
  fix: writing pto consumer only if not already set by idel controller
  moving things around in gui
  adding generic vehicle
  adapting GUI: move all PTO-related inputs to a single tab in Vehicle editor
  correcting user manual
  bugfix: don''t chagne state on dry-ryn
  adding validation to rundata for pto activations
  amt shift strategy: perform upshift if gear is below desired gear and engine speed is still acceptable
  'switch off' pto idle losses in case one of the other ptos is active (road sweeping, pto during drive, pto during standstill); sum all ptos as pto-consumer in mod data
  fix testcases: provide driver data (due to changes required for roadsweeper applications in driver, gearbox, shift strategy)
  fix: only increase velocity if gear & engine speed during roadsweeping is below target speed (higher engine speeds are allowed)
  fix: loading and writing vehicle file (json)
  loading and saving pto cycle
  adding missing files in testdata
  adding missing file, extend file writing
  implementing sideloader pto activation during drive
  adding pto-roadsweeper parameters to GUI and writing to JSON file
