Cleanup net peers output

[cryptoquick]

Task summary
net peers prints a lot of extraneous information that's either redundant or not useful.

Acceptance criteria

• net peers has no duplicate Multiaddrs
• net peers does not show localhost or loopback ip4 and ip6 routes

Other information and links
Compare the output of lotus net peers:

...with the output of forest net peers:

A lotta extra junk!

• Be sure to note: It's okay to have multiple routes, for example, we might have an external ip4 route and an external ip6 route to a peer, so this task isn't as simple as selecting a single route per peer, we still need to return the vector, even though the majority are a single external ip4 route.
