Add support for Nostr Connect

[tiero]

Hello! Love the client, really good stuff!

Would love to use Nostr Connect to login, in without having to paste my private key into the browser.

Is pending merge, but the protocol should not change much, so it's safe to be integrated.
nostr-protocol/nips#153

Here you can find a TypeScript SDK to easily integrate it.

Mobile Apps integrating it are Daisy, Arc, Marina, and Nostrum and potentially many more soon.
