How to use the @parcel/utils.registerSerializableClass function in @parcel/utils

// First, create the main cache directory if necessary.
  await fs.mkdirp(dir);

  // In parallel, create sub-directories for every possible hex value
  // This speeds up large caches on many file systems since there are fewer files in a single directory.
  let dirPromises = [];
  for (let i = 0; i < 256; i++) {
    dirPromises.push(
      fs.mkdirp(path.join(dir, ('00' + i.toString(16)).slice(-2))),
    );
  }

  await Promise.all(dirPromises);
