refactor: update libp2p-yamux and fix breaking changes

 - Passing a logger to MuxerInit is now required
 - Passing a logger to yamux()({logger:...}) is now required

See: #120

Update dependencies and fix various breaking changes introduced by those
dependency updates:

- Change type of Conn to Duplex<Uint8Array | Uint8ArrayList>
- Pass default logger to yamux as it's now required.
 - We need to pass a Uint8ArrayList to the WebSocket it-ws.
