WS2812B Reset Time Update: Enhanced compatibility with newer WS2812B chipsets
- Updated default reset time from 50μs to 280μs across all platforms
- Fixes intermittent issues where only first LED responds to fill_solid() and similar operations
- Addresses GitHub issue #2067: WS2812B strips showing ~80% failure rate with latest FastLED
- Updated 18 ARM platform clockless controllers (Apollo3, STM32, SAMD, Teensy, etc.)
- ESP8266 clockless controller timing updated for better reliability
- Maintains backward compatibility while supporting newer WS2812B chip revisions
STM32F4 Support Added: BlackPill STM32F411CE and STM32F4 family support
- Added STM32F4 platform detection using canonical STM32F4 preprocessor define
- Full GPIO pin mapping support for WeAct Studio BlackPill V2.0 (STM32F411CE)
- Consolidated STM32F1/STM32F4 pin definitions to reduce code duplication
- Added CI testing with GitHub Actions build badge for continuous validation
- Compatible with PlatformIO platform and Arduino framework
