calculate_unscaled_emitter_power_mW()

fl::u32 calculate_unscaled_emitter_power_mW	(	fl::span< const fl::u8 >	codes,
		fl::u8	emitter_count )

Charge already-solved physical output bytes in source emitter order: RGB, RGBW, or RGB + warm white + cool white.

Used by the managed pipeline's power hook; it must not apply legacy RGB-to-RGBW conversion a second time.
