add strict mode to tag transform basic filtering so as to remove any special case processing/manipulation for the output-multi object. this way it only exports and validates tags found in the export list. also change tag transform matching for relation members to allow typeless relations. this is needed because the intial relation filtering that output-multi does (which only exports tags specified by the user) will strip the type tag (if not in the export list) from a relation before sending it on to the relation member filtering.
