* Successful coordinate transformations might leave errors on stack We pop and log them after using the transformer. Resolves #2353 * Test error clean up * Skip test for GDAL <= 3.3 * Use CPLErrorReset * Call CPLErrorReset in _err wrappers * Remove obsolete exception handler * Note changes from gh-2487
