UPDATED LIBRARY and GUIDE: NeoPXL8 Adds ESP32-S3 Support

UPDATED GUIDE: Adafruit NeoPXL8 FeatherWing and Library

NeoPXL8 is a hardware/software combo for controlling up to eight concurrent NeoPixel strands. Splitting the task 8 ways—and leveraging DMA features of current microcontrollers—makes for buttery smooth animation. It also helps with “improbable” topologies like our Ooze Master 3000 project.

Version 1.2.0 of the Adafruit_NeoPXL8 library adds Espressif ESP32-S3 support (S3 only, not S2, C3 or original ESP32). And since ESP32 chips have super-flexible pin-MUXing, any of the existing NeoPXL8 adapters (FeatherWing M0, M4 or NeoPXL8 Friend) can work here without modification.
