Return the Geometry Buffer from a valid XmlBLOB buffer
\param blob pointer to the XmlBLOB buffer. \param size XmlBLOB's size (in bytes). \param blob_geom on completion this variable will contain a pointer to the returned Geometry Buffer (NULL if no Geometry was defined within the XmlBLOB) \param blob_size on completion this variable will contain the size (in bytes) of the returned Geometry Buffer
\sa gaiaIsIsoMetadataXmlBlob
\note the returned Geometry Buffer corresponds to dynamically allocated memory: so you are responsible to free() it before or after.
