Only lowercase and even-length tag values are stored as binary BLOBs. Previously there was an error which search results from being returned if the tag value was mixed-case and could be interpreted as hex. A new database migration has been created to repair the `tag` table for existing relays. fixes: https://todo.sr.ht/~gheartsfield/nostr-rs-relay/37
