Show more metadata about selected Volume

[kephale]

When you select a volume in tree view, the attributes shown in the Properties panel are primarily things to edit. However, there are some read-only attributes that are interesting, like image size, pixel size, etc..

This could be easily implemented in the Properties class.

Labeling this as 1.0.0 it isn't critical, but is pretty easy and people always want the metadata info for volumes

@ctrueden this is a little weird, but can we have @Parameters that are static? I was hoping to follow the pattern we have here

sciview/src/main/kotlin/sc/iview/commands/edit/Properties.kt

Lines 130 to 133 in a17d4ee

	/* Volume properties */
	@Parameter(label = "Timepoint", callback = "updateNodeProperties", style = NumberWidget.SLIDER_STYLE+",group:Volume")
	private var timepoint = 0

and just add more @Parameters for at least voxel dimensions and image size that get updated by the Node but cannot be changed in the Properties panel.
