This takes advantange of the latest features in go-cid, peer.ID and go-multiaddr and makes the Go types serializable by default. This means we no longer need to copy between Pin <-> PinSerial, or ID <-> IDSerial etc. We can now efficiently binary-encode these types using short field keys and without parsing/stringifying (in many cases it just a cast). We still get the same json output as before (with minor modifications for Cids). This should greatly improve Cluster performance and memory usage when dealing with large collections of items.
