Add setpoint_shift_mode DTP1007 (DTP Step) in Climate

Hi, I have various GEWISS GW1X795H thermostats that shift the setpoint with a DPT 1.007 datapoint data and therefore I would need to be able to set the correct setpoint_shift_mode. In this case with “0” lowers the setpoint by 0.5C and “1” raises the setpoint by 0.5C. Is it possible to implement it?
