added new feature: --nsec

Now one can run a command like this to fire-and-forget, i.e. send a message
without a config file and forget everything after message has been sent:

nostr-commander-rs --nsec nsec1SomeStrangeString --add-relay "wss://some.relay.net/" --publish "some text"

or

nostr-commander-rs --nsec $NSEC --add-relay "wss://some.relay.net/" --publish - < SOMETEXTFILE.txt
