Introduce APDU/TPDU trace decoder

This introduces a new pySim.apdu module hierarchy, which contains
classes that represent TPDU/APDUs as exchanged between
SIM/UICC/USIM/ISIM card and UE.

It contains instruction level decoders for SELECT, READ BINARY and
friends, and then uses the pySim.filesystem.Runtime{Lchan,State} classes
to keep track of the currently selected EF/DF/ADF for each logical
channel, and uses the file-specific decoder classes of pySim to decode
the actual file content that is being read or written.

This provides a much more meaningful decode of protocol traces than
wireshark will ever be able to give us.

Furthermore, there's the new pySim.apdu_source set of classes which
provides "input plugins" for obtaining APDU traces in a variety of
formats.  So far, GSMTAP UDP live capture and pyshark based RSPRO
live and pcap file reading are imlpemented.
