also @npub107jk7..., would it be possible to extract just the NIP-42 auth manager from grimoire and add it to applesauce?

I'm thinking something like `new AuthenticationManager(localStorage)` that would act as a signer that only signs NIP-42 events. then I would extend the `RelayPool` to take an `authSigner` that would automatically be prompted for authentication requests
Then as long as the authentication request queue was stored in an RxJS observable. any UI library could easily display it
