Missing currentSpeedLimit in RouteLegProgress

[BroxZaphod]

I am trying to show the speed limit for the current user position.

When creating the route object i provide the 'maxSpeed' infos in the annotations but missing the currentSpeedLimit in RouteProgress.currentLeg

The underlying issue is that the MapboxDirections from Flitsmeister is not including the maxspeed info. We would need to add this to the RouteLeg.

@KasparElmans input on this would be welcome, I gave this a try, but the repository did not build on my machine after several tries. I have seen you have a SPM PR in the making, but it seems to be bit stale.
