Magnetometer calibration

Implementation ported from the MCG HAL.
Algorithm gathers a sample set and computes the hard iron bias offset
and the soft iron bias matrix inversion. Once the calibration data is
set it's used for the following events until a better calibration data
is generated. Samples are continuously gathered.
