 right now CarpetIOASCII computes the "local" coordinates from the lower
 boundary coordinate of each patch and CCTK_DELTA_SPACE. This does not work
 (as expected) for multipatch.

 It would be good to add an option to use grid::x etc instead. Ideally as
 both a parameter and an option in the '{}' to choose at runtime and per
 variable what to do (eg. to keep the r coordinate around for spherical
 patches).
