Michael Auchter 34531895a0 limitlessled: Use LedControllerPool
This change is in preparation for adapting this component to support multiple
LimitlessLED bridges. Ultimately LedControllerPool helps to maintain the
mandatory 100ms pauses across multiple controllers so messages are reliably
received.
