Add SlicerANTsPy

The ANTsPy library wraps image processing framework ANTs in Python. It provides
modules tailored for integration with SlicerMorph extension and workflow.

It includes reading and writing of medical images, algorithms for registration,
segmentation, statistical learning. SlicerANTsPy extension makes ANTsPy
available inside 3D Slicer, and provides graphical user interface to some
of its common functionalities such as interactive registration, batch (group wise)
registration, template creation and tensor-based morphometry via Jacobian
analysis (WIP).

It provides some convenience features such as optionally initializing all
registrations via landmarks.
