Add HA Light Target

How often to send color updates to HA lights (0.5-5.0 Hz). Lower values are safer for HA performance.
Smooth fade duration between colors (HA transition parameter). Higher values give smoother but slower transitions.
Skip sending color updates when the RGB delta is below this threshold. Reduces HA traffic for near-static scenes.
Effective output brightness below this value turns lights off completely (0 = disabled)
Map LED ranges to HA light entities. Each mapping averages the LED segment to a single color.
