Registration function seemingly not doing anything

Hello @fsalv ,

I am trying to reproduce your results training a model from scratch and am having some trouble. One thing I've noticed is this:

The ``register_imgset`` function L160 returns the input ``imgset`` instead of the registered version of the images ``imgset_reg``. See here: https://github.com/EscVM/RAMS/blob/bc16e52b8e2d7b5e23560e14045f13f181d03f77/utils/preprocessing.py#L160

To me this seems like a mistake. Maybe I am missing something?

If this is a mistake, could you please advise if you think your pretrained models were affected?
