Attachments: capture of HDR and SDR image

Currently, kwin has supported upstream Wayland color management protocol and also HDR display. So we need spectacle to also support HDR screenshot.

capture of HDR and SDR image

I tried to take a screen capture of an HDR image(youtube video paused) and SDR.  The result was actually worse than the SDR version. It seemed to have a lot less color detail than the SDR image.

Visually on my screen the HDR image looked great and had obviously more color detail than the SDR image.

I did edit the image afterwards to crop it and add annotations, but this did affect the colors in the image at all.
