Adding script to restride data and bvecs

[karanphil]

Quick description

This is a script to validate if data has the "correct" strides 1,2,3. If not, it applies the correct transformation to get it to 1,2,3. If bvecs are given (in the case of DWI), the script will also apply the transformation on them, assuming the bvecs are in the right space. If it's not the case, the option --validate_bvec can be used to ensure the bvecs are in the right space to begin with, and then apply the right transformation to bring them to 1,2,3 along with the data.

I wonder if --validate_bvec should be the default option. Thought? @frheault @arnaudbore @mdesco
