sniffer functionality fixed buffer

It is possible to use sniffer.py to sniff the phone-simcard-communication.

To be fixed: The buffer size read is fixed and the data is only send
over USB if the buffer max length is reached. which means we don not
get the last bytes of the transaction.
This should be changed in one of the next commits. Maybe the former
simtrace code can give some inspiration on this topic.
