Displays a rotating rainbow pattern on the Servo 2040's onboard LED bar.

Press "Boot" to exit the program.

NOTE: Plasma WS2812 uses the RP2040's PIO system, and as
such may have problems when running code multiple times.
If you encounter issues, try resetting your board.

Create the LED bar, using PIO 1 and State Machine 0
