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

Changes

- removes err-code from dependencies
- adds @libp2p/interfaces@3.2.0 to dependencies
- uses CodeError in place of err-code
