This PR extends the Relay class in such a way that it can be flexibly used as a Man-in-the-Middle.
It adds a new Command-Line Flag (--mitm) which takes a path to a Python File that contains a function
get_MitM(), which, when called, produces an object with ahandleInPDUand ahandleOutPDUmethod. This object is then used by the Relay-VICC as a Man-in-the-Middel, meaning it passes any packets to thesehandle-Methods and relays the result of them (instead of the original packets).For the MitM flag to work properly, the path which is given to it needs to be in Python's load path (eg PYTHONPATH).
The --mitm flag only applies when the Relay type is used. If the Relay is used without specifying a MitM-Module, the default
RelayMiddlemanis used, which does nothing at all. TheRelayMiddlemanclass may be used by the user to create custom middlemans by inheriting from it.
