ENH: Wrap reorder projections filter for vector and CUDA images

[arobert01]

This is needed to reproduce in Python the behavior of the rtkspectralonestep application when subsets are used.

There are a few warnings when loading the new packages:

Can you address them or should I?

[arobert01]

I replaced WRAP_ITK_ALL_TYPES (which already include ITK_VECTOR) by WRAP_ITK_REAL. I hope it will solve the warnings otherwise I'm not sure to be able to fix them.

It seems to have worked, thanks a lot!
