I think we should follow [this structure](https://scikit-image.org/docs/stable/api/skimage.registration.html) for our registration module. @John-P what do you think?

Closing this PR as this has been resolved in separate PRs.

@vqdang @mostafajahanifar @John-P this is ready for review. I have added model trained on CoNiC as well.
