[Feature request] Label api for better documented 3D objects

[traverseda]

One of my big complaints with openscad is how hard it is to document or re-use anything. It would be nice if libfive had some kind of "labeling" feature that let you draw a "point of interest".

I'm imagining something a bit like sketchfab's labels: https://sketchfab.com/3d-models/little-pirates-island-6d7fc2df62e7415aae9585f258f5efb8
