Installed NeoPixelBus V2.8.0, tried to compile NeoPixel_RP2040_PioX4.ino and it blows up on these lines...

NeoPixelBus<NeoBgrFeature, NeoRp2040Pio1X4Ws2811Method> strip1(120, 15); // note: older WS2811 and longer strip
NeoPixelBus<NeoGrbFeature, NeoRp2040Pio1X4Ws2812xMethod> strip2(100, 2); // note: modern WS2812 with letter like WS2812b
NeoPixelBus<NeoGrbFeature, NeoRp2040Pio1X4Ws2812xInvertedMethod> strip3(100, 4); // note: inverted
NeoPixelBus<NeoGrbwFeature, NeoRp2040Pio1X4Sk6812Method> strip4(50, 16); // note: RGBW and Sk6812 and smaller strip

If I comment the each one out it just crashes on the next one complaining that NeoRp2040Pio1X4Ws2811Method was not declared in this scope.

Any help would be appreciated; I went and bought ~$150 worth of SK6812 Strips and Power Supplies based on this page https://www.arduino.cc/reference/en/libraries/neopixelbus-by-makuna/ saying "This library is compatible with ALL architectures."

Thank you.
