We can replay the gossip messages in order and reconstruct the network as it
would have looked like at a specific time in the past. This tool does just that,
including the 2 weeks passive pruning logic (if a channel hasn't seen an update
in the last two weeks they are considered dead). It is not considering channel
closes that are signaled by spending the funding output, since that'd require
tracking the outputs.
