This introduces an "APDU source" for pySim-trace which enables the
decoding of APDUs that are copy+pasted from elsewhere, for example
APDU logs in text form created by proprietary tools, or to decode
personalization scripts or the like.

On my debian unstable system with wireshark 4.6.2-3, the pyshark_gsmtap
APDU source misses to report any ATRs, as those are not part of what's
reported with the 'gsm_sim' display filter. This is due to
wireshark.git commit bcd82e2370d18e20983b378d494964d89c191cef first part
of the 4.6.0 release, which splits the ATR dissection into a separate
sub-dissector.
We cannot use the seemingly logical 'gsmtap.type == 4' instead, as old
wireshark simply bypasses any output for the gsmtap header if the SIM
sub-dissector is used.
Hence, 'gsm_sim || iso7816.atr' is something compatible with older and
newer wireshark versions.

The "TCA Loader" is a freeware utility program published by the
Trusted Connectivity Alliance for testing SCP80, SCP81, SCP02 and SCP03
in UICCs. It can generate text log files of the APDUs it exchanges;
let's add this file format to pySim-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.

So far we supported
* GSMTAP live traces via a UDP socket
* RSPRO traces from pcap files (or live)
We were lacking support for reading GSMTAP stored in pcap, which
is what this patch implements.

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.
