adding more testcases for further configurations, refactor tests, added assertions for powertrain configuration

in case the interpolate search is not successful (i.e., difference in electric power too high), search again (with interpolate search) and increas y value

make max startgear available from strategy, if vehicle is halted make calculations with maxStartGear (in case the downshift in the braking phase before resulted in a different gear at vehicle stop)

fix in combustion engine when vehicle stops

refactor engine stop/start: hybrid strategy can always stop ICE during drive (except P1), ESS during standstil as for conventional

adding testcases for EM-Loss-map

   selecting best option: if brake power is already set (we found an operating point) - do not select an option where the torque is too high or too low
   selecting best option: if target speed is below start speed and target speed is already reached do not allow solutions with too high engine speed

electric motor: limit max recuperation if battery is almost full (available capacity close to 0 (1e-9))

hybrid controller: add information on gearbox in case of overload (helpful for debugging cases with vehicle torque limitations)

at-gearbox: provide additional information in response

hybrid strategy: additional entry were ICE is at max torque (so that a previously searched operating point can be used again)

additional exclusion criteria in hybrid strategy: in case vehicle speed is below min speed during gearshift do no shift, if vehicle propulsion limit is set also check if this is exceeded.
gearbox: set additional fields in response (dryrun)
driver: handle the case that the engine speed is too high after a valid acceleration is found (due to vehicle propulsion limit)
