/**
 * Calculates the `geohex`, the H3 cell-id, of the supplied geo_point at the specified precision.
 * The result is long encoded.
 * Use `TO_STRING`
 * to convert the result to a string,
 * `TO_LONG`
 * to convert it to a `long`, or
 * `TO_GEOSHAPE`
 * to calculate the `geo_shape` bounding geometry.
 *
 * These functions are related to the `geo_grid` query
 * and the `geohex_grid` aggregation.
 *
 * @example
 * FROM airports
 * | EVAL geohex = ST_GEOHEX(location, 1)
 * | STATS
 *     count = COUNT(geohex),
 *     centroid = ST_CENTROID_AGG(location)
 *       BY geohex
 * | WHERE count >= 10
 * | EVAL geohexString = TO_STRING(geohex)
 * | KEEP count, centroid, geohexString
 * | SORT count DESC, geohexString ASC
