fix: unhandled promise rejection when async work done after handshake #2

Merged

If you do async work after invoking it-handshake but before awaiting
on any of the fields of the response, an unhandledPromiseRejection can
occur if the stream.sink method rejects.

This manifests itself in libp2p vis multiformats/js-multistream-select
as:

(node:82951) UnhandledPromiseRejectionWarning: Error: already piped
    at Object.sink (node_modules/it-pair/index.js:10:24)
    at module.exports (node_modules/it-handshake/src/index.js:15:30)
    at module.exports (src/select.js:10:57)
    at Dialer.select (src/index.js:27:12)
    at Context.<anonymous> (test/dialer.spec.js:43:26)

Also:

  • Updates all deps
  • Removes node Buffers in favour of Uint8Arrays
