* Improved peer ID construction and usage * peer id object is directly passed to the network no need to cast from a string to an ID * don't base64 encode the peer id when loading from public key * use proper multiaddr address - keep multiaddr object into peerstore instead of string - update network code to use new multiaddr lib - update tests and example * don't instanciate peerstore object in constructor This has side effect where the same peerstore is used for different instance of Libp2p * add connect method to basic_host * use zaibon's fork of sbuss/py-multiaddr * lint
