162ba3af3e pySim-trace: mark card reset in the trace
The trace log currently does not contain any information about card
resets. This makes the trace difficult to follow. Let's use the
CardReset object to display the ATR in the trace.

531894d386 move Runtime{State,Lchan} from pySim.filesystem to new pySim.runtime
Those two are really separate concepts, so let's keep them in separate
source code files.

21caf32e3d 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.
