TElSSHForwardingIntercept represents a base class which allows users to intercept SSH connections.
If you want to intercept an SSH connection, i.e. catch data from the SSH channel, process it and then send further,
you should create a descendant of TElSSHForwardingIntercept and perform all operations inside the descendant.
Call ChannelRead and SocketRead to get data from the SSH channel. Then process the data and send it further using WriteToSocket and WriteToChannel methods, accordingly.
