refactor: replace err-code with CodeError

Replaces [err-code](https://github.com/IndigoUnited/js-err-code/blob/master/index.js) with [CodeError](libp2p/js-libp2p-interfaces#314)

Related: [#1269](libp2p/js-libp2p#1269)

Changes (only affect peer-id package)

- added @libp2p/interfaces@3.2.0 to the to use the new CodeError export
- removes err-code from dependencies
- uses CodeError in place of err-code
