LEDs: add rainbow effects

Setting the headlights to Solid with white, and then setting the taillights to Rainbow Cycle allows users to replicate the "Mullet" effect from the Float package. Using Rainbow Cycle on the front and the back replicates the "Rave" effect from the Float package. Also added an RGB Fade effect which smoothly transitions between colors. Feature: Add the Rainbow Cycle and RGB Fade LED effects.
