Jumping red pixels #12

I noticed that patterns like this one have a random red sparkle. We (well, the people who are smarter than me in the Wokwi discord and googled it properly) tracked this down to a bug in FastLED with fill_rainbow that's been tracked at least as far back as 2019.

It's a very interesting bug - it only affects hue 60 and saturation 240, and it's also affected by an LED's position in the array.

It looks as though this is fixed in this commit - updating FastLED to the latest master and see whether the simulation looks better.

Actually, I just realized that this isn't even the right repo for this, and may not be reproducible on an ESP32. I'll need to update the preview builder instead.
