Computes the magnetic field from part of the IGRF13 magnetic field model

Only accounts for period 2000-2020. Other times uses the limits. If within the select time period, linear interpolation in time is used

Latitude cutoff very near the poles using only a single value

Note that no conversion from geocentric uvw to geodetic uvw is performed, so some small artifacts are to be expected

Also note that positions close to the poles are given the same field-values
