do not return any result.

Unclear how iPhone 8 plus example is provided as there is no such occurrence in https://ipolcore.ipol.im/cp2/showDemo?demo_id=77777000278 and https://ipolcore.ipol.im/api/demoinfo/staticData/demoExtras/77777000278/PRNU_compare_two_images.zip.

For IPOL practicing make a prototype of what we would like the demo to be but without the algorithm itself. Seems quite clear to me now.

Related to Improve_websites_thanks_to_open_source/issues/622.

DDL.json:

   "build": {
      "build1": {
         "url": "https://lemnoslife.com/BEN/PRNU_compare_two_images.zip",

works fine, as with default parameters that are:

Denoiser: Wavelet
Zero-meaning operation: False
Wiener filtering: False
Spectrum equalization: False

I get an identical result on my demo (77777000503) as the one I am interested in (77777000278).
