/**
 * Divides a {@link LineString} into chunks of a specified length.
 * If the line is shorter than the segment length then the original line is returned.
 *
 * @function
 * @param {FeatureCollection|Geometry|Feature<LineString|MultiLineString>} geojson the lines to split
 * @param {number} segmentLength how long to make each segment
 * @param {Object} [options={}] Optional parameters
 * @param {Units} [options.units='kilometers'] Supports all valid Turf {@link https://turfjs.org/docs/api/types/Units Units}
 * @param {boolean} [options.reverse=false] reverses coordinates to start the first chunked segment at the end
 * @returns {FeatureCollection<LineString>} collection of line segments
 * @example
 * var line = turf.lineString([[-95, 40], [-93, 45], [-85, 50]]);
 *
 * var chunk = turf.lineChunk(line, 15, {units: 'miles'});
 *
 * //addToMap
 * var addToMap = [chunk];
