lon_lat_to_cartesian

This function converts geographic coordinates, given as longitude and latitude in degrees, to Cartesian coordinates (x, y, z) assuming a spherical Earth model.

Provides efficient geospatial thinning algorithms to reduce
the density of coordinate data while maintaining spatial
relationships. Implements K-D Tree and brute-force distance-based
thinning, as well as grid-based and precision-based thinning methods.
For more information on the methods, see Elseberg et al. (2012)
