Jump example not working

Hello @hierynomus,

I noticed that DirectConnection class is not present in the current working version "0.27" thus I am not able to use some parts of the code.

Example URL: https://github.com/hierynomus/sshj/blob/master/examples/src/main/java/net/schmizz/sshj/examples/Jump.java

Specifically, I cannot use:

-----

import net.schmizz.sshj.connection.channel.direct.DirectConnection;
DirectConnection tunnel = firstHop.newDirectConnection("localhost", 22);
ssh.connectVia(tunnel);

----

The objects are not found. Please advise.

Thanks.
