Correct detectormaps for spatial effects as well as wavelength effects

It looks as if we're not updating the DetectorMaps' fibre trace *columns* in calibrateWavelength. An old RHL problem, but it may be why the vector plots are weird (or why you built them off arcs!)

CalibrateWavelengthTask updates the wavelength solution and writes a new detectormap with that correction, but changes in the spatial direction are not currently determined and written to that detectormap.

Update the code to provide that correction.

Side note: it may be sensible to rename the task given would correct for both wavelength and spatial directions, but this is less important.
