Add option to display/hide square around face tags

[alexthamm]

Is your feature request related to a problem? Please describe.
All faces in my pictures are tagged (using digikam). When opening a picture with a tagged face, a square is shown around the face. This is not helpful because I know the people in my pictures. It's rather annoying as I'm interested in the actual pictures and not the location of the faces in the pictures.

Describe the solution you'd like
It would be great if we could configure on the settings page whether the square is displayed or not.

Sounds good to me.
It should be added here:

pigallery2/src/frontend/app/ui/gallery/lightbox/controls/controls.lightbox.gallery.component.html

Line 58 in 2295455

*ngIf="facesEnabled && activePhoto && activePhoto.gridMedia.Photo.metadata.faces && activePhoto.gridMedia.Photo.metadata.faces.length > 0">
