STD WS2813 Level Shifter Hack

Description
A simple level shifter to control WS2812/WS2813/Neopixel with a 3.3V GPIO pin
Instead of using level shifter ICs or MOSFETS you can simply sacrifice 1 LED to do the level shifting for you. The voltage for that sacrificed LED needs to be lower than 5V. Using a diode to reduce voltage to 4.3V works.
Note that the brightness of that LED will be lower than that of the other LEDs. So you may want to hide it with insulation tape or something.
