Adding binary thinning 3d algorithm

[sychen52]

I recently created this package: https://github.com/sychen52/binary_thinning_3d_cuda
It extracts the skeleton of a 3d binary mask. Do you think it is a good idea to add this functionality to this repo?

Hey!

Thanks for the amazing implementation. It makes much more sense to integrate it https://github.com/vmtk/SlicerExtension-VMTK here. We can also use this to add a clDice custom loss in MONAI for skeleton supervision.
