New dataset and raster band classes are defined specifically for the
purpose of being write-only. In particular, you cannot read back data
from these datasets, and writing must occur in a pretty specific order.
That is, you need to write all metadata (projection, georef, etc) first
and then write the image data. All bands data for the first scanline
should be written followed by all bands for the second scanline and so on.
Creation supports the same virtual subfile names as CreateCopy() supports.
