ws2812: add support for 160MHz cortex-m processors

Browse Source 
This adds hardware timing support for driving WS2812 LEDs on Cortex-M microcontrollers running at 160MHz (such as the STM32U585).

- Updated `go:generate` directive to include 160MHz.
- Generated the corresponding `ws2812_writeByte160` assembly routine.
- Added a switch case in `WriteByte` to handle generic 160MHz processors.
