sensor calibration delete temperature (CAL_ACCx_TEMP, CAL_GYROx_TEMP, CAL_MAGx_TEMP)

- this was an experiment to casually monitor sensor offsets relative to temperature, but now that all calibration offsets can be adjusted post-flight the stored temperature can be misleading
 - deleting to save a little bit of flash (and storing the temperature wasn't useful)
