Legacy layer does not support virtual stacks

[ctrueden]

There are a couple legacy plugins that open data as virtual stacks (File > Import > Stack From List and File > Import > TIFF Virtual Stack). However IJ2 will try to create memory resident stacks from the resulting ImagePluses. The legacy layer should detect when a legacy created ImagePlus is backed by a virtual stack and create an Img that is also of a virtual type.

I'm pretty sure I fixed this one before I left. Can you retest?

I will, in the course of the work after uploading a new ImageJ2 (which required quite a few preparations in fiji-compat, Fiji_Updater and imagej-launcher). I also vaguely remember that this was fixed, but we still need to reconcile imglib2-ij with imagej-legacy... So all of this might be fixed in one monster flurry of commits.

I did not have time to re-test, but I saw the code. So I am closing it!
