Added readings after calculating hard iron offset.

I used this library for mpu9250 github.com/bolderflight/invensense-imu and just calling the methods for getting the data. | |

The displayed heading seems consistent with the measured mx and my. These values, however, seem wrong: The modulus of the magnetic field changes as you turn the device. It should not. Either you are doing something wrong while getting the readings, or there is something magnetic next to (or on) your device that affects the local field.
