Initial lookahead for FPGA interchange.
Currently the lookahead is disabled by default because of the time to
compute and RAM usage. However it does appear to work reasonably well
in testing. Further effort is required to lower RAM usage after initial
computation, and explore trade-off for cheaper time to compute.
