"""
This script re-orders the values in the x,y and z columns of a text file (e.g. a bathymetry .pts/.xyz file) such that they conform to a true .xyz format readable by GDAL and openable in QGIS.

In many cases the data in an "xyz" file falls foul of the GDAL requirement that:
“Cells with same Y coordinates must be placed on consecutive lines. For a same Y coordinate value, the lines in the dataset must be organized by increasing X values.”
