Color mode propagates to all images in Imviz

[Jdaviz-Triage-Bot]

Reporter: pllim

I cannot tell if this is intentional or a bug that snuck in or always been there. Workflow to reproduce:

1. Load 2 data into Imviz. I used the ImvizDitheredExample notebook but I don't think it matters what data.
2. Blink once back to A.
3. Change its color mode to monochromatic in Plot Option. Here I also picked a color from the palette but I don't think it matters which color.
4. Blink back to B.

Expected outcome: Image B should have remained in colormap mode in grayscale.

Actual outcome: Image B is now also monochromatic and set to blueish somehow.

If you change A back to colormap, then B also changes back.

colormode is a per-viewer setting in glue. This is made a little more obvious in multiselect mode and will also be improved in the upcoming re-ordering (to split viewer and layer options). If we ever want per-layer colormode, we need to request that upstream.
