This is a client-side implementation of LSB (least significant bit) steganography.

It does not work for images with transparency.  I don't know why.

```html

  (async () => {

    const base64 = /* some base64 image data goes here */;

    const watermark = await createWatermark(base64, 'John Doe');

    

    const image = new Image();

    image.src = watermark;

    document.body.appendChild(image); // displays watermarked image on screen

    const hiddenText = await readWatermark(watermark, 8);

    console.log(hiddenText); // John Doe

  })();
