Creates a geometry lookup (GLT) file from a raster

1	raster_to_GLT(x)

`x`	Raster* The raster containing the geographic information to be used as the basis for the GLT.

This function produces a two-band brick where the pixel values for the first band are the column numbers, and the pixel values for the second band are the row numbers of the corresponding pixels in the input Raster* file.
