wgs84conv is a accurate & fast Earth-Fixed Earth-Centered (ECEF) to Geodetic (lla) convert module based on:
Karl Osen. Accurate Conversion of Earth-Fixed Earth-Centered Coordinates to Geodetic Coordinates.[Research Report] Norwegian University of Science and Technology. 2017. hal-01704943v2
And with pybind11 & carma, this module also support Python binding.
