Changes between 2.5 (released 2024-12-28) and 2.4 versions:
* New magnetic models provided
+ World Magnetic Model 2025, wmm2025; this covers the period
2025-2030. This is now the model returned by
MagneticModel::DefaultMagneticName and is default magnetic
model for MagneticField (replacing wmm2020 which is only valid
thru the end of 2024).
+ World Magnetic Model High Resolution 2025, wmmhr2025; this is a
high-resolution version of wmm2025 including terms up to degree
133 (as opposed to 12 for wmm2025).
+ International Geomagnetic Reference Field (14th generation),
igrf14, which approximates the main magnetic field of the earth
for the period 1900-2030.
* Update CMake's cmake_minimum_required to 3.17.0 (to facilitate
integration with Qt projects).
* For GEOGRAPHICLIB_PRECISION > 2, readarray treats doubles as
approximations to exact decimal constants.
