 These values are collected from GeodTest which is associated with GeographicLib:
     https://zenodo.org/record/32156

 The conversion to C++ array format is done using this Python script:
     https://github.com/adl1995/boost-geometry-extra/blob/master/geographiclib-dataset-parse-inverse.py

 Geodesic scale (M12) is absent from the GeodTest dataset, so it is manually generated
 using GeographicLib using this C++ script:
     https://github.com/adl1995/boost-geometry-extra/blob/master/geographicLib-direct-small_angles.cpp
