Update WS2812X ESP32 RMT timing for WS2815 compat #795

  1. Update WS2812X ESP32 RMT timing for WS2815 compat 

    The existing values are out of spec for WS2815 which results in flickering, especially on longer cable runs.

These new RMT values are still closer to ideal WS2812B specs than the current I2S WS2812X timing (about 310us / 940us).
