Was listening to the #[0] video this morning with #[1] this morning about being able admit or deny users to a relay via an API. Seemed like a cool idea to do it over nostr so threw this togather where a relay admin can allow or deny users by publishing a note. There is no NIP at the moment just made up the format, will formalize if there is interest. It is a gRPC extension for the nostr-rs-relay. Will add an http api to it as well.

Can use this to publish notes for now:
