[Feature Request] Add options to View Broadcasted relays for events and re-broadcast events

[Sakhalinfox]

Could we add an option to view the list of relays that have seen or not seen the Event ID's that were published by the user or anyone else's event ID's as well. I feel this could be useful to know if our events / posts / notes / DM's were broadcasted to the relays were use or if they need re-broadcasting in case a relay was unreachable or down or if the relay does some restrictions or event handling.

It could be placed under the Other options menu as two different options 'View event broadcast info' and 'Broadcast Event'. The former option could be used to input an Event ID or Note ID and get a list of seen and unseen relays (relays that have seen or not seen the event amongst your added relays).

The latter option could allow the user to input event ID's to broadcast to relays that haven't seen it. Possible allow a comma separated user input of event ID's if multiple event ID's need to be re-broadcasted.
