Hi,
I have added a package for the Nomacs Image viewer. It is built with
plugins but not with HEIF or PSD support. I tried creating a package for
the libqpsd package but was unable to get the qt plugin to appear in the
right location. It seems to build fine with `./pre-inst-env guix build
--rounds=2 nomacs` so hopefully its good enough for inclusion despite these
missing features.

+    (description "Nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images.
+
+Nomacs features semi-transparent widgets that display additional information such as thumbnails, metadata or histogram. It is able to browse images in zip or MS Office files which can be extracted to a directory. Metadata stored with the image can be displayed and you can add notes to images. A thumbnail preview of the current folder is included as well as a file explorer panel which allows switching between folders. Within a directory you can apply a file filter, so that only images are displayed whose filenames have a certain string or match a regular expression. Activating the cache allows for instantly switching between images.
+
+Nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, exposure. It has a pseudo color function which allows creating false color images. A unique feature of Nomacs is the synchronization of multiple instances. With this feature you can easily compare images by zooming and/or panning at the exactly same position or even by overlaying them with different opacity.
