This PR adds support for controlling servos. For example, on the Arduino Uno it should be able to control up to 6 servos jitter-free when using all available PWM pins. I haven't added support for setting a position in degrees, mainly because this varies by servo and it's probably necessary to configure the bounds in some way. Therefore, I added just SetMicroseconds. This makes the API possible to use and leaves the possibility of adding a SetPosition in the future.
