Re: [magnetometer] Provide API to access uncalibrated magnetometer values

Bias = hard_Iron bias, distortion of magnetic field strength due to 
presence of magnet or similar material.
So [x,y,z] = magnetic field (without hard-iron compensation), and 
[x_bias, y_bias, z_bias] are the estimated hard-iron bias along the 3 
axes.
We can then think, _uncalibrated = _calibrated + _bias. 
For the VR use case, presence of magnet will affect the bias values, 
and developer can take some action.
