Closes #197

Third commit is the real meat of this change, it is probably easier to review commit by commit due to the movement of the math functions of another file in the first commit.

I have tested this idea and observed negligible or no change in the calibration matrix given the same input.

I haven't changed anything about how the sensors use magneto, other than causing a net reduction in memory usage. I leave it up to other people to experiment with increasing the number of samples now that we're no longer memory constrained.
