IGpioPin does not allow access to PWM functions

[BryanCrotaz]

IGpioPin does not give access to all PWM functions.

In Workbench, the Servo demo should take an IGpioPin in the constructor, not a GpioPin.

Alternatively explain in docs how to get a GpioPin instance from
Pi.Gpio[bcmPinNumber]

Try a cast. The readme gives the following example:

   var range = 100;
   var pin = (GpioPin)Pi.Gpio[BcmPin.Gpio24];
   pin.PinMode = GpioPinDriveMode.Output;
   pin.StartSoftPwm(0, range);

Oh that's soooo dodgy! Assuming that the implementation of an interface is an exact class is ripe with error potential.

Yes. I don't know why the maintainers designed it so. Maybe they'd like to chip in?

I've submitted a few improvement PRs but they're withering on the vine
