fix: make local peer id optional

`[email protected]` will remove the `localPeer` argument from the `secureInbound` and `secureOutbound` methods of the `ConnectionEncrypter` interface. Unfortunately the `js-libp2p` monorepo has a depdendency on this module so the change cannot be released until this module is compatible... with the unreleased change. This PR tests the first argument to `secureInbound` and `secureOutbound` to ensure that it is actually a `PeerId`. If not it shuffles all the arguments along by one place. This PR can be reverted and the first argument removed once `[email protected]` is released.
