XOR/XNOR Gates

3 builds compete: 3-tick 8-bit XOR/XNOR gates.

Fastest

#	Build	Latency	Volume
1	8-bit alpha XOR Gate 8 copies of a 1-bit build, stacked	3 ticks	320 blocks per copy
2	8-bit alpha XOR Gate 8 copies of a 1-bit build, stacked	3 ticks	384 blocks per copy
3	8-bit XOR Gate 8 copies of a 1-bit build, stacked	3 ticks	400 blocks per copy
