Discussed in #4104

There is a correct way to convert a ddf tensor accepted by Monai's warp block into an itk VectorImage accepted by itk's WarpImageFilter.

This conversion is defined and tested here:

I would like to use this conversion code, and I think it is generally useful since it correctly handles fiddly details like transposing the tensor and reversing the order of elements in each vector. Would a pull request moving it from the test code into the MONAI library be welcome?
