Model specific colormaps

We can set a default colormap per model. For example: qsm -> hot, t1 methods -> parula etc.

QSM is an interesting one. It ought to have a bipolar colormap, because the values can legitimately go negative. However all QSM papers I’ve ever read stick to greyscale. Maybe by choosing a sensible default you can get people to start publishing sensible figures!

I've always been a fan of the Blue-White-Red map for images that are centered around zero (e.g. percent difference maps), but not sure if it would be a good contrast for QSM. It gives a clear indication of what's the 0 value (white), and blue being low values / red being high values makes immediate sense, for me at least (cold/hot).
