 * # GeoTIFF Reader
 *
 * ## Description
 * This class reads a GeoTIFF file and returns a list of GeoTIFF images.
 * Implements the {@link FeatureIterator} interface.
 *
 * ## Usage
 * ```ts
 * import { ALL_DEFINITIONS, EPSG_CODES, GeoTIFFReader } from 'gis-tools-ts';
 * import { FileReader } from 'gis-tools-ts/file';
 *
 * const fileReader = new FileReader(`${__dirname}/fixtures/utm.tif`);
 * const geotiffReader = new GeoTIFFReader(fileReader, ALL_DEFINITIONS, EPSG_CODES);
 * ```
