/**
 * Calculates the area of a GeoJSON polygon or multipolygon with high accuracy.
 *
 * This function uses several strategies for accurate area calculation:
 * 1. First attempts to use geodesic calculations via geographiclib-geodesic
 * 2. Falls back to @turf/area if geodesic calculation fails
 *
 * The geodesic approach provides better accuracy by calculating areas on the WGS84 ellipsoid,
 * compared to @turf/area which uses spherical approximation.
 *
 * @param geojson - A GeoJSON Polygon, MultiPolygon, Feature, or FeatureCollection
 * @returns Area in square meters
