NIP66 NIP50 relays

Issue #1

NOTICE from wss://feeds.nostr.band/: error: unknown feed

nostr.band feeds are tricky because the root domain connects like a relay, but does not actually behave like a relay. Only it's sub paths act like relays, and I'm still trying to figure out how to handle this in a way that doesn't require manual treatment. It would be better if feeds.nostr.band refused to connect.

Issue #2

NOTICE from wss://relay.noswhere.com/: internal error on filter 0

Internal issue it seems.

Issue #3

Some search relays don't implement search correctly and return events that do not include the search string. N filters presently just enable supported_nips to be filtered against.

While I do run a variety of tests, things like NIP-50 are difficult to validate because false negatives are almost expected (maybe it's a new relay and the term being searched is not there yet...)

I am open to suggestions about how to handle this situation.

Overall

Every relay returned advertises NIP-50 support via NIP-11. 0/50 returned are missing NIP-50 from their NIP-11.

Aside: Funny that there are presently 50 NIP-50 relays :D
