### Multi-volume lightbox mode for `mrview`

`mrview`'s lightbox view mode now supports concurrently visualising multiple volumes for a single image across a grid. To enable this feature, switch to lightbox mode (View → Lightbox), then open the View tool (Tool → View) and select the _Cycle through volumes_ tick-box. A user can additionally modify the _Volume increment_ size to control the range of visible volumes.

This should prove useful for quick visual inspections of multi-volume data:
