Nyall Dawson 1729531773 Don't transform z coordinates by default
Since z coordinates can represent potentially any height
unit and reference point, it's not safe to assume that they
always represent height in metres relative to the ellipsoid.

Instead, leave z values untouched by default with geometry
transforms, and make transforming z an optional parameter
