ComputeShiftPolygon: Exception when less than 2 gears are given, GUI UpdatePic checks for Gear-Count > 1

Added PTOEngineCycleController, Split up the Cycle-Classes into several files, removed IPowertrainSimulation Interface, Inherited PowertrainDivingCycle from StatefulProviderComponent

a smaller tolerance causes that the next simulation interval will be smaller than the minimum simulation interval and thus cause other issues (e.g. high inertia torque from engine, etc.)

fix testcases: enable writing mod file in aux-test, use constant for driving cycle exceeded before brake

fix testcase for reading json files: initially used wrong indizes for gears, adaptations to new powersplit/serial AT gearbox (ratios, #gears)
