is_lonlat

This function checks whether a pair of coordinate vectors represent
geographic longitude and latitude values. The function returns `TRUE`
if all longitude values are within -180 (- tolerance) and 180 (+ tolerance)
and the latitude is within -90 (- tolerance) and 90 (+ tolerance).

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.
