feat: add CodeError (#314)

Adds [CodeError](libp2p/js-libp2p#1269) to errors.ts

Related: libp2p/js-libp2p-crypto#284 (comment)

Added public to props and code to match AbortCode style.

Also recently added the custom [Error.name](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/name) property to [code-err](https://github.com/tabcat/code-err) implementation.
