[Feature request] Accept bytes input

I'm generating an audio file on the Frontend and sending to Deno in base64,
It would be cool if there's a function that can accept bytes input directly.

Current workaround is to save it as a temp file first.

export async function getMp3Duration(audioFile: File) {
  await Deno.mkdir("./data", { recursive: true });
  const audioFilePath = await Deno.makeTempFile({
    prefix: "audio-file-",
    suffix: ".mp3",
    dir: "./data",
  });
  const arrayBuffer = await audioFile.arrayBuffer();
  const bytes = new Uint8Array(arrayBuffer);
  await Deno.writeFile(audioFilePath, bytes);

  try {
    const ms = await AudioDuration.duration(audioFilePath);
    return ms;
  } finally {
    Deno.remove(audioFilePath);
  }
}
