The purpose of this contest is to create the smallest possible file that is
recognized as a valid raster GeoPackage by GDAL.

The following rules must be followed:
- the file must be readable with "gdalinfo -checksum contest.gpkg" (exactly this commandline)
  where contest.gpkg is the candidate file.
- the above command must report that the driver used to open the file is the GeoPackage driver.
- the above command must report, without any displayed warning or error, at least one raster
  band and the checksum of the band(s)
- any GDAL version with GeoPackage raster support can be used (i.e. GDAL 2.0 or later) at the
