/**
 * Reads Potree datasets.
 *
 * ## Supported formats
 *
 * This source currently reads legacy Potree datasets (a `cloud.js` files and multiple `.hrc` and
 * data files). Data files may either be in the BIN format or LAZ files.
 *
 * LAZ decompression is done in background threads using workers. If you wish to disable workers
 * (for a noticeable cost in performance), you can set {@link PotreeSourceOptions.enableWorkers} to
 * `false` in constructor options.
 *
 * Note: this source uses the **laz-perf** package to perform decoding of point cloud data. This
 * package uses WebAssembly. If you wish to override the path to the required .wasm file, use
 * {@link sources.las.config.setLazPerfPath | setLazPerfPath()} before using this source.
 * The default path is {@link sources.las.config.DEFAULT_LAZPERF_PATH | DEFAULT_LAZPERF_PATH}.
