Remote Control Cleanup

Instructions
Some "other" developers have been working on the remote control car project exercise:csharp/remote-control-competition. You have been called in to clean up the code.
1. Separate concerns between the car itself and the telemetry system
Refactor the RemoteControlCar class to move to separate out telemetry methods and properties accessed via a Telemetry property.
var car = new RemoteControlCar();
car.Telemetry.Calibrate();
car.Telemetry.SelfTest();
car.Telemetry.ShowSponsor("Walker Industries Inc.");
car.CurrentSponsor
// => "Walker Industries Inc."
car.Telemetry.SetSpeed(100, "cps");
car.GetSpeed()
// => "100 centimeters per second"2. Prevent other code taking too many dependencies on the Telemetry type
Ensure that the Telemetry instance cannot be created outside the scope of the car.
3. Prevent other code from taking dependencies on the Speed struct
Ensure that the Speed struct cannot be used outside the scope of the RemoteControlCar class.
4. Prevent other code from taking dependencies on the SpeedUnits enum
Ensure that the SpeedUnits enum cannot be used outside the scope of the RemoteControlCar class.
