Allows data to be interpolated along the field line before doing the transform to the poloidal plane. Routine assumes input is in field-aligned space. This is the not default for BOUT++ >= v4.

I'm pretty sure we require numpy for the pylib stuff, so we can just safely import it here. I think we also require scipy as well

Allows data to be interpolated along the field line before doing the
transform to the poloidal plane.
Also fixes for v4 onwards due to change in meaning of
nz(i.e. we no longer have the duplicate point).
