buildTwoWhiteAllocationQ16()

bool fl::buildTwoWhiteAllocationQ16	(	const colorimetric_response::EmitterProfile &	profile,
		const i32(&)	white1_xyz[3],
		const i32(&)	white2_xyz[3],
		WhiteAllocationPolicy	policy,
		TwoWhiteAllocationQ16 *	out )

Derive the allocation for three primaries plus two white emitters.

white1_xyz / white2_xyz are each white's XYZ at full drive, in s16.16, the same working domain the rest of the pipeline carries.

False on the profiles buildRgbSolveMatrixQ16 rejects, and when either white lands so far outside what the primaries express that the per-pixel bounds would overflow their accumulators – see kTwoWhiteMaxColumn in the implementation, which a real white emitter is nowhere near.
