Add creation options flag to gdal_calc.py
|Reported by:||bkg||Owned by:||hobu|
This patch adds creation options support to the gdal_calc.py script. Options can be passed using --creation-option or --co. It would have been preferable to use -co instead in keeping with the convention of most utilities, but OptionParser only allows for single character short flags. Argparse does support this use, but is only available in the standard library for Python 2.7 and up.
