airspeed_ms45xx_i2c
MS45XX differential or gauge type of pressure sensor for e.g measuring airspeed. This sensor module is using the MS45xxDO digital pressure sensor with readings via I2C. Needs to be a versions with 14bit pressure and 11bit temperature data output. If the airspeed reading is badly calibrated, use the MS45XX_PRESSURE_SCALE to compensate. Use the MS45XX_AIRSPEED_SCALE only to change air density.
