my morning's work on #realy is going to be modifying the relay request processing policy

what i'm adding now is a feature so when auth is enabled, certain kinds of events, which i'm calling "Directory" events, will be permitted without auth, and implemented by changing the "AcceptReq" method so that if the filters in the request have all of the kind fields except the directory kind are removed and only events of the Directory kind wil be returned, as well as sending a "notice" that the relay is only returning directory events

this will enable paid relays to still deliver things like deletion and user profile metadata and follow and mute lists and user private relay (nip-17) associations so the users presence on other relays can be learned without being a paid user
