Upgrade aegir and add package lock file (#5)

* chore: upgrade aegir (libp2p#1566)

Updates aegir, fixes all linting and dep issues.

Co-authored-by: achingbrain <alex@achingbrain.net>

* Fix linting errors

* Add package-lock.json

* fix: use @libp2p/keychain module instead of bundling source code (libp2p#1569)

The @libp2p/keychain module has the keychain code split out from this module so use that instead of bundling the code here.

It's also dropped it's dependency on `node-forge` so it's now only in `@libp2p/crypto`.

* Fix dependencies

* Avoid upgrading go-libp2p for interop tests
