/**
 * # OSM File Reader
 *
 * ## Description
 * Parses OSM PBF files
 * Implements the {@link FeatureIterator} interface
 *
 * ## Usage
 * ```ts
 * import { OSMFileReader } from 'gis-tools-ts/file';
 *
 * const reader = new OSMFileReader('./data.osm.pbf');
 *
 * // pull out the header
 * const header = reader.getHeader();
 *
 * // read the features
 * for (const feature of reader) {
 *   console.log(feature);
 * }
 *
 * // close the reader when done
 * reader.close();
 * ```
