Overlay's coordinate system should be independent between images #1619

At the moment, loading two images side-by-side forces their overlay to use the same coordinate system. There's no way to load two images and show different coordinate systems in each panel.

As a note here: we should be careful about making the changes here as region wcs is sync’d with the viewer too.

In my point view having all labels showing same wcs reference system is not a bad idea. But I am open to hear the feedback from the science team.

@kswang1029 are there situations where this will break things? is it always possible to translate between systems?
