Peer should impliment IEquatable<T> interface.

[rybakatchya]

Right now if you have peer in a list and call List.Contains(Peer) it will cause GC allocations. Implementing IEquatable on the Peer struct will resolve this issue. See https://medium.com/@semuserable/c-journey-into-struct-equality-comparison-deep-dive-9693f74562f1

Would putting the peers into a Dictionary<uint PeerID, Peer Peer> solve this? Is there any reason you need to have the Peers in a List like that?

[rybakatchya]

I could do that, but the same problem will happen if you use Dictionary.ContainsValue. Really no reason to not implement IEquatable and I have already done so locally.

I have no objections to this, do you want to do a PR and I'll merge it in?
