wave8Transpose_16_bf1()

FL_OPTIMIZE_FUNCTION FL_IRAM void fl::wave8Transpose_16_bf1	(	const u8(&)	lanes[16],
		const Wave8ByteExpansionLut &	lut,
		u8(&)	output[16 *sizeof(Wave8Byte)] )

BF1: chipset-aware direct encode for 16-lane Wave8 (#2548 deep-dive).

Bypasses the byte_lut. Uses the algebraic identity output_bit(s, p, lane) = M0_p XOR (input_bit_(7-s) AND D_p) where W0/W1 are the bit-0/bit-1 waveform patterns extracted from the lut. Bit-identical to wave8Transpose_16 for ANY Wave8 chipset. The bit-transpose of input bytes is computed ONCE (not 8× per symbol). Measured 9 651 → 4 465 µs/frame (2.16×) vs baseline on P4 v1.3.
