Mod required for Raspberry Pi Zero 2W

I am running the example code on a Raspberry Pi Zero 2W. In order for the code to work properly, I had to change this line:

https://github.com/adafruit/Adafruit_CircuitPython_IS31FL3741/blob/08a529607189dbb127dad16b9adbba7781757738/examples/is31fl3741_rgbswirl.py#L23

to:

```py
is31.pixel(
x,
y,
colorwheel(((y * 13 + x) * 1 + wheeloffset) % 0x100),
)
```

This mod was not required on an Feather RP2040.

Start with examples/is31fl3741_rgbswirl.py at the linked line and compare its behavior on a Raspberry Pi Zero 2W and an Feather RP2040. Check whether the reported expression change is required for the example to run correctly on both platforms; done means the example works without a platform-specific modification.
