ob_tran doc: fix/clarify semantics of o_lat_p/o_lon_p
This is a super confusing topic, but from experiments, and in particular with
the example of Fairgrieve projection, o_lat_p and o_lon_p are the coordinates
of the North pole of the unrotated geographic CRS expressed in the rotated
geographic CRS.
This is different from defining a 'new pole', which would be the coordinates
of the rotated North pole expressed in the unrotated CRS.
