extension to Laplace coords

[jordandekraker]

Potentially, these coordinates could be extended into SRLM and DG smoothly using a warp. This could be done by registering a binary GB label to a binary GM+STLM+DG label. Ideally this would be done directly after computing coords, and it should be noted that the result would likely no longer be strictly Laplacian. Will experiment with this in the coming days.
