bugfix in supercap: calculation of max discharge power, ensure initial soc is higher than min soc, fix in powertrain builder calculating aux buffer in case of supercap

revert changes in velocity gearshift preprocessor
correct name of generated file in testcase

refactor electric motor: move transmission effiency and transmission ratio from power map transformation to explicit calculation step
rename B2 ... positions to E2...
add more colums to .vmod and .vsum for electric motor component

update .vmod and .vsum: consistent naming of EM related fields (use drive instead of motoring, correct units, add fields for em losses and em transmission losses
.vsum: add ice off time share, correct units, adding energy demand electric aux high voltage system

update expected sum files with new column, update engine-only mod files (previous version contained wrong columns)

adding missing files: gearshift position  and shiftlineset (Effshift AT), formerly part of Voith shift strategy

refactoring to use 'gearshift position' instead of uint (AMT) as well as uint and bool (AT) gearboxes. GearList contains ordered list of gears
adapt shift strategies and interfaces.

move conversion of electric motor full-load curve from lookup method in full-load curve to full load curve reader to match with electric map and drag curve
