Title: get_mask should default to shape of generating image

While it is possible to have a dendrogram structure without the image it is generated from, it makes sense to have the structure know at least about the shape of the image from which it was generated. The pixel coordinates within each node don't really make sense without that information.

`get_mask()` should work by default.
