implemented this check in the base class for all components

do not require a hybrid controller, so the test-powertrain class can be used for other purposes as well

remove initialize method in gearbox that takes a gear as argument and issues a dry-run request with a different gear.
this approach caused errors because the internal 'previous state' of components might be modified.
instead, a separate simple test-powertrain is used to calculate the necessary values without altering the state of the actual powertrain

(cherry picked from commit 571fe081)

set ICE values and gearbox efficiency / axlegear efficiency only if the respective component is present in the powertrain

moddata: calculate ice max load time share and gearshift count only if ICE and transmission are present

refactoring lookup method for vehicle group based on input, return tuple of vehicle group and vocational for report

remove testcases which are not useful (model data cannot be simulated as it only demonstrates syntax)

more testcases, minor refactoring

restructuring source code writing results: move classes which are used in MRF and CIF to a common folder/namespace

calculation of CD/CS weighting is only a dummy implementation

adding empty classes for results writer, adding binding,
extending testcase to check the correct results writers are created
