/** \brief Returns a list operation::CoordinateOperation between two CRS,
 * using intermediate codes.
 *
 * The list is ordered with preferred operations first.
 *
 * Deprecated operations are rejected.
 *
 * The method will take care of considering all potential combinations (ie
 * contrary to createFromCoordinateReferenceSystemCodes(), you do not need to
 * call it with sourceCRS and targetCRS switched)
 *
 * If getAuthority() returns empty, then coordinate operations from all
 * authorities are considered.
 *
 * @param sourceCRSAuthName Authority name of sourceCRSCode
 * @param sourceCRSCode Source CRS code allocated by authority
 * sourceCRSAuthName.
 * @param targetCRSAuthName Authority name of targetCRSCode
 * @param targetCRSCode Source CRS code allocated by authority
 * targetCRSAuthName.
 * @param usePROJAlternativeGridNames Whether PROJ alternative grid names
 * should be substituted to the official grid names.
 * @param discardIfMissingGrid Whether coordinate operations that reference
 * missing grids should be removed from the result set.
 * @param considerKnownGridsAsAvailable Whether known grids should be considered
 * as available (typically when network is enabled).
 * @param discardSuperseded Whether cordinate operations that are superseded
 * (but not deprecated) should be removed from the result set.
 * @param intermediateCRSAuthCodes List of (auth_name, code) of CRS that can be
 * used as potential intermediate CRS. If the list is empty, the database will
 * be used to find common CRS in operations involving both the source and
 * target CRS.
 * @param allowedIntermediateObjectType Restrict the type of the intermediate
 * object considered.
 * Only ObjectType::CRS and ObjectType::GEOGRAPHIC_CRS supported currently
 * @param allowedAuthorities One or several authority name allowed for the two
 * coordinate operations that are going to be searched. When this vector is
 * no empty, it overrides the authority of this object. This is useful for
 * example when the coordinate operations to chain belong to two different
 * allowed authorities.
 * @param intersectingExtent1 Optional extent that the resulting operations
 * must intersect.
 * @param intersectingExtent2 Optional extent that the resulting operations
 * must intersect.
 * @return list of coordinate operations
 * @throw NoSuchAuthorityCodeException
 * @throw FactoryException
