FastLED Platform: ARM SAMD51 (d51)

SAMD51 (Feather/Itsy M4, Wio Terminal) support.

Files (quick pass)

fastled_arm_d51.h: Aggregator; includes fastpin_arm_d51.h, clockless_arm_d51.h, and SPI core where applicable.
fastpin_arm_d51.h: Pin helpers for SAMD51.
led_sysdefs_arm_d51.h: System defines for SAMD51.
clockless_arm_d51.h: Clockless WS281x driver for SAMD51.
README.txt: Historical notes on tested boards.

Notes:

Higher clock speeds and interrupt policy can affect jitter; prefer short critical sections.
Typical settings: FASTLED_USE_PROGMEM=0; consider enabling interrupts with careful ISR timing.

Optional feature defines

FASTLED_USE_PROGMEM: Default 0.
FASTLED_ALLOW_INTERRUPTS: Default 1. Enables FASTLED_ACCURATE_CLOCK when 1.

Define before including FastLED.h.
