Add more colors to RGB LED component

Id love to take this up if no one is working on it already.

[SteveDesmond-ca]

💯 go for it!

Is this issue still pending implementation? I'd like to work on it if so.

[SteveDesmond-ca]

Feel free to give it a shot!

@SteveDesmond-ca, I believe we will indeed have to implement PWM as in issue #7 before we can close this one, since there is no way to set the voltage to values other than 0 or 1. Please correct me if I'm wrong, but the PWM implementation would go in the IPinInterface and its implementations, right?

[SteveDesmond-ca]

Yeah, I think we need a PWMManager or something like that on each pin, to handle the toggle timing, and the pin can then have a Strength (better name?) getter/setter that calls into PWM.

My guess is that sysfs will be too slow, so you'll need to use the experimental flag on the Factory to enable System.Devices.Gpio (and therefore the memory mappings) as the backend.

PWM has been implemented as of v2.0.0-beta.2 this afternoon, and I'm planning on adding some helpers/extensions for this over the next week.

[SteveDesmond-ca]

As of v2.0.0-beta.3 this afternoon, a new method RGBLED.SetColor() can take any System.Drawing.Color and adjust software PWM accordingly for each of the RGB pins.

Docs will be updated for v2 final.
