encoded_string_api_4    encoded_string_api_4: An encoded route to
                        illustrate the 'osrmr::decode_geom()' function.
                        After decoding all points on the route are
                        available as wgs84 coordinates. Decoding varies
                        on the API version of OSRMR. This version is
                        decoded using API v4.
encoded_string_api_5    encoded_string_api_5: An encoded route to
                        illustrate the 'osrmr::decode_geom()' function.
