With #19 recently merged, OpenAthena uses Kip Crossing's geotiff library instead of GDAL as a pre-requisite

One downside of this implementation: OpenAthena is no longer able to detect if a provided GeoTIFF is rotated or skewed

Before PR #19, OpenAthena would print an error and stop if the provided GeoTIFF was rotated or skewed. The software used the dydx and dxdy parameters of the GDAL .GetGeoTransform() function

An equivalent solution must be found and implemented for OpenAthena with the geotiff library
