Greatly improve raster output performance for large runs on
parallel filesystems by writing one TIF file per rank along
with a VRT file. Writing to /path/to/foldername/filename.vrt
creates the directory foldername if it does not exist and
writes data to files /path/to/foldername/filename.%d.tif
No changes are needed to read VRT files.
The VRT TIF files are written in tiled format as there is no
performance penalty when writing but a dramatic performance
increase when reading small areas from very wide rasters.
