This mode allows full control of addressable RGB LEDs connected to the ESP32.
Use it to configure the LED type, fill colors, run test animations, or manipulate individual pixels.
Supports all major chipsets via FastLED (WS2812, APA102, SK6812, etc.).

• All protocols supported by FastLED are available (~50 protocols).
• config sets the pin, the brightness and the number of LEDs.
• fill and set support multiple formats for <color>:
  • HTML name: red, blue, silver, darkblue...
  • Hex: #FF00FF, 0x00FF00
  • Decimal RGB: 255 0 255
• set could also be used with on or off.
• set starts counting from 0, which means the first LED on the strip has index 0.
• scan tries known chipsets/protocols and run animation to find a working match.
• setprotocol shows the massive list of supported LED protocols, type the index of the protocol to chose it
• If unsure about your LED model, use scan or try setprotocol.
