/**
 * M150: Set Status LED Color - Use R-U-B-W for R-G-B-W
 *       and Brightness       - Use P (for NEOPIXEL only)
 *
 * Always sets all 3 or 4 components. If a component is left out, set to 0.
 *                                    If brightness is left out, no value changed
 *
 * With NEOPIXEL_LED:
 *  I<index>  Set the NeoPixel index to affect. Default: All
 *
 * With NEOPIXEL2_SEPARATE:
 *  S<index>  The NeoPixel strip to set. Default is index 0.
 *
 * Examples:
 *
 *   M150 R255       ; Turn LED red
 *   M150 R255 U127  ; Turn LED orange (PWM only)
 *   M150            ; Turn LED off
 *   M150 R U B      ; Turn LED white
 *   M150 W          ; Turn LED white using a white LED
 *   M150 P127       ; Set LED 50% brightness
 *   M150 P          ; Set LED full brightness
 *   M150 I1 R       ; Set NEOPIXEL index 1 to red
 *   M150 S1 I1 R    ; Set SEPARATE index 1 to red
