 SELECT ST_AsText(ST_GeomFromGeoHash('IamNotAGeoHash_ThisIsABug')) returns
 POINT(7.23566132272554 -65.0109736310277). It appears that there is no
 check in decode_geohash_bbox,
 https://postgis.net/docs/doxygen/2.5/dc/dc0/lwalgorithm_8c_source.html#l00584,
 for characters that are not defined in base32.
