/**
 * Computes the Haversine distance between two points on a sphere of unit length 1. Multiply the result with the radius of the sphere. (For instance Earth's radius is 6371km)

 * @category Metrics
 * @param {number[] | Float64Array} a - Point [lat1, lon1] in radians
 * @param {number[] | Float64Array} b - Point [lat2, lon2] in radians
 * @returns {number} The Haversine distance between `a` and `b`.
