Subject: [PATCH] feat: add CodeError (#314)

Adds [CodeError](https://github.com/libp2p/js-libp2p/issues/1269) to errors.ts

Related: https://github.com/libp2p/js-libp2p-crypto/pull/284#issuecomment-1324005434

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.
