Add a trivial benchmark of calculating routes on today's graph

Sadly rust upstream never really figured out the benchmark story,
and it looks like the API we use here may not be long for this
world. Luckily, we can switch to criterion with largely the same
API if that happens before upstream finishes ongoing work with the
custom test framework stuff.

Sadly, it requires fetching the current network graph, which I did
using Val's route-testing script written to test the MPP router.

Check the PK of the source of an error before closing chans from it

When we receive an error message from a peer, it can indicate a
channel which we should close. However, we previously did not
check that the counterparty who sends us such a message is the
counterparty with whom we have the channel, allowing any
connected peer to make us force-close any channel we have as long
as they know the channel id.

This commit simply changes the force-close logic to check that the
sender matches the channel's counterparty node_id, though as noted
in #105, we eventually need to change the indexing anyway to allow
absurdly terrible peers to open channels with us.
