This is a feature request for a hidden watermark tool in the BQM, so that we
can conceal a hidden plain-text or image watermark into our photos.

I am aware of a wavelet-based method and a fourier-based one.

You can do this using Mathmap or G'MIC, however those tools do not work in
batch. It would be awesome if digiKam let us do this!

Reproducible: Always
