Subject: [PATCH 1/2] Fix TypeError thrown when specifying interpolator for
 ANTsRegistrator

`interpolator` was passed twice to `ants.transform` when it was
specified as an additional argument in
`ANTsRegistrator(transformation_params={'interpolator': 'value'})`. This
change makes sure to pass it only once, and that the specified value
takes precedence over the default.
