Not working encoded strings from Open Routing Machine

[josephkandi]

I tried this string

}gqefAridwgFrYEAhfA{@jDsAxBoBzBaDtB{iAX{c@EsU]uf@?_WR~@tPlTFfg@?jUNj|@eBtu@K?z]cAjLkDlJuFjGyG`IyCjIsAlM?|k@v@|dArQbv@k@jIpA?

and it didnt output the right coordinates. I did divide them by 10 and i got the right coordinates just before adding them to the CLLocationCoordinate2D array

When I try the string with google's polyline decoder : https://developers.google.com/maps/documentation/utilities/polylineutility , it decodes to invalid GPS locations : (373.3211 , -1220.3076).

It seems OSRM uses a higher precision than google : Project-OSRM/osrm-backend#713

I might work on being able to change the precision factor, or I can accept a merge request doing so :)

@josephkandi you can use v1.1.0 to decode polylines from OSRM :

// OSRM uses a 6 digit precision
let polyline = Polyline(encodedPolyline: "ak{hRak{hR", precision: 1e6)
// or 
let coordinates: [CLLocationCoordinate2D]? = decodePolyline("ak{hRak{hR", precision: 1e6)
