How to use wasm-lz4 - 2 common examples

async initialize(extensionPoint: ExtensionPoint): Promise {
    const { bagPath, cacheSizeInBytes } = this._options;
    await decompress.isLoaded;

    if (bagPath.type === "remoteBagUrl") {
      extensionPoint.progressCallback({ fullyLoadedFractionRanges: [] });
      let approximateSize = 0;
      const fileReader = new BrowserHttpReader(bagPath.url);
      const remoteReader = new CachedFilelike({
        fileReader,
        cacheSizeInBytes: cacheSizeInBytes || 1024 * 1024 * 200, // 200MiB
        logFn: (message) => {
          log.info(`CachedFilelike: ${message}`);
        },
        keepReconnectingCallback: (reconnecting: boolean) => {
          extensionPoint.reportMetadataCallback({
            type: "updateReconnecting",
            reconnecting,
          });

initialize = async (initialize: InitializeMessage): Promise => {
    await decompress.isLoaded;
    this._bag = await open(initialize.bagPath);
  };
