Publicly expose underlying net.Conn connections

Created by: mirceapasoi

I'm using the Acceptor from quickfixgo to maintain a bunch of FIX connections, and I'd like to implement IP whitelisting functionality.

From what I can tell, the Acceptor maintains a private net.Listener for managing the TCP connections: https://github.com/quickfixgo/quickfix/blob/master/acceptor.go#L140

Would it be possible to publicly expose the underlying net.Conn connections, so I can access RemoteAddr for whitelisting?
