feat: change api to async / await (#112)

BREAKING CHANGE: All places in the API that used callbacks are now replaced with async/await. The API has also been updated according to the latest `interface-transport` version, https://github.com/libp2p/interface-transport/tree/v0.6.0#api.

-> JavaScript implementation of the TCP module for libp2p. It exposes the [interface-transport](https://github.com/libp2p/interface-connection) for dial/listen. `libp2p-tcp` is a very thin shim that adds support for dialing to a `multiaddr`. This small shim will enable libp2p to use other different transports.
