+/// BasicTest example to demonstrate massive parallel output with FastLED using
+/// ObjectFLED for Teensy 4.0/4.1.
+///
+/// This mode will support upto 42 parallel strips of WS2812 LEDS! ~7x that of OctoWS2811!
+///
+/// The theoritical limit of Teensy 4.0, if frames per second is not a concern, is
+/// more than 200k pixels. However, realistically, to run 42 strips at 550 pixels
+/// each at 60fps, is 23k pixels.
