Add regionprops features to graph

[cmalinmayor]

New Feature request: More properties on graph

Description

We are already using regionprops to extract the node centroids from the segmentation. Regionprops also extracts other features that we could/should add to the graph for free and can later be used for tracking. Things to consider:

• 2D and 3D cases have potentially different features
• Optionally adding the input data to get intensity features
• Adding edge features on differences of node features
