Replace 2-d interpolation filter pipeline with equivalent ITK filter
@isensee implemented the 2-d interpolation in Python and noticed that our whole filter pipeline for the 2-d interpolation is already covered by ITK's ApproximateSignedDistanceMapImageFilter. I did a pixel-wise check and can confirm that the results are identical.
Test Plan: Did a pixel-wise comparison of several interpolations.
