Handle event deletions in redux

NIP9 defines deletion events.

kind 5

• e tag, delete that event
• a, <kind>:<pubkey>:<d-identifier>

Events should also have a k tag for each kind being deleted. I guess for filtering purposes.

Research on nos.lol says they process deletions by deleting the event, but only tell clients about the deletion if the client is listening with a query that would include the kind 5 deletion event. So a subscription for the pubkey of the author would work, but a subscription for author + kind 30397 will not. The deletions will never be seen by the client.

This needs some design. We need to actively subscribe to kind 5 events, which means we need to think about how to do that. I'll put this on pause for now as it's not critical for the next few weeks.
