App 2.27.3: read the cruise control target speed, log it raw

The head unit names a vendor float AAD_EPTCCTRGTSPD (0x2160A15B),
the cruise control target speed by its name. EVHardware reads it raw;
the Logs tab lists each change with time, speed and gear, to establish
the unit and the off value on the car. Emulator only (absent there).
