Later on in this series, we will need to know during path finding if an
edge we are traversing was derived from a blinded payment path. In
preparation for that, we add a BlindedPayment member to the
`unifiedEdge` struct.
The reason we will need this later on is because: In the case where we
receive multiple blinded paths from the receipient, we will first swap
out the final hop node of each path with a single unified target node so
that path finding can work as normal. Once we have selected a route
though, we will want to know which path an edge belongs to so that we
can swap the correct destination node back in.
The routing package implements authentication+validation of channel
announcements, pruning of the channel graph, path finding within the network,
sending outgoing payments into the network and synchronizing new peers to our
channel graph state.
