This a wrapper function around link{pgblobs::getBlob}. It assumes that rasters in the datacube are stored as GeoTIFF files. This function gets the GeoTiff file from the datacube and converts it into a normal raster file.

This functions checks if the raster file allready exists, if it exists is does not load the file from the datacube since this is time consuming. If the user wants to update the file, use argument 'update=TRUE'

The GeoTiff will be deleted after writing the raster file.
