LEDs: add Rainbow Fade and Rainbow Cycle effects

Using "Solid" on the headlights and "Rainbow Cycle" on the taillights can replicate the "Mullet" setting on the Float package. Using "Rainbow Cycle" on both replicates the "Rave" effect from the Float package. Feature: add Rainbow Fade and Rainbow Cycle effects
