Daniel Agar 185f22b094 geo_lookup: copyright header consistency and minor update
Minor consistency fixes for the copyright header and update the tables to current. PX4Buildbot will periodically update the tables automatically from this point.

Daniel Agar 9aa7991654 geo_lookup: upgrade table size (2 bytes per element) and add testing
- updated table to 2 bytes (int16) per element and scaled the inclination/declination/strength tables to use most of the range without being too awkward
 - tables have been extended to include the full latitude range
 - expanded the API slightly to offer declination/inclination in both degrees/radians and the magnetic strength in Gauss and Tesla
 - generated some simple testing that verifies interpolation between points
