chore: replace err-code with CodeError (#53)

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/[email protected] to dependencies
- uses CodeError in place of err-code
