Title: Add TIFF tags for specifying min/max sample values.

This will write the minimum and maximum cell values into the TIFF
file itself. It's worth noting that GDAL ignores this information
and calculates the min/max itself (when -stats is provided).

The hope is that ArcMap can use this information.
