// Group LEDS for enhanced performance

// Group_Leds = 2; and higher: group this number of LEDs together (color is copied from 1st LED of each group)

// Tips:
// Set Num_Leds to the total Number of LEDs in your strip
// In the Software you use, adjust the number of LEDs to the total Number of LEDs divided by the grouping:
// For example for an 80 LED strip with Group_Leds = 2; you would set it to 40 LEDs in the Software.
// With Group_Leds = 4; you would set it to 20 LEDs.
// The higher the Group_Leds number, the better the performance / FPS will be.

- LED color order
- Serial speed
- Serial timeout length
- Grouping of LEDs to increase Performance

There are also optional settings to clear the LEDs on reset or flush the incoming serial buffer after every latch. This latter option is enabled by default to help with flickering when using WS2812B LEDs.
