What does this PR do?
gdal_calc should raise an error if it could not create output dataset, instead of raising an unexpected error when executing some code like
myOut.SetGeoTransform(GeoTransformCheck).gdal/swig/python/gdal-utils/osgeo_utils/gdal_calc.py
Lines 363 to 373 in d5957ab
I notice that the gdal c++ library will put an error message to stderr, for example
ERROR 4: Attempt to create new tiff file /w/a.tif failed: No such file or directory. But it will be useful if we detect this error in python side, because gdal_calc is not only an command line tool but a library.
