Small change to the reductor module to try to get past 180 MHz. Previously BRAM
outputs were going directry into a LUT-based ternary adder which was causing timing problems. Added a layer of flip-flops, so instead of BRAM -> LUT -> FF we have BRAM -> FF -> LUT -> FF. This increases core latency by (number_of_supporting_modular_multiplications + number_of_exponent_bits) ticks.
