Disconnect timeout option for default and non-default relays

[hzrd149]

Is there an option to set a timeout for how long rx-nostr will keep a relay connection open after its no longer needed?

I've started using rx-nostr in my client to fetch events and users profiles. this usually involves connecting to random one-off relays and I would like it to not imminently close the connection after it gets an EOSE because usually there is another REQ I need to make to the same relay a few seconds later

This would also be good to have for any relays I've authenticated to. since the client has gone through the trouble of authenticating it doesn't make sense to close the connection for a while

I've set the connectionStrategy to lazy-keep but this only seems to effect default relays
