Segment anything with our Napari integration of Meta AI's new Segment Anything Model (SAM)!

SAM is the new segmentation system from Meta AI capable of one-click segmentation of any object, and now, our plugin neatly integrates this into Napari.

We have already extended SAM's click-based foreground separation to full click-based semantic segmentation and instance segmentation!

At last, our SAM integration supports both 2D and 3D images!
