When the method del_lchan is called, closed_channel_nr still contains a dict
that contains the channel number under the key 'logical_channel_number'.
This will lead to an exception. We must extact the channel number from
the dict before we can use it with del_lchan. (See also
created_channel_nr)

In their infinite wisdom, the authors of the EIRENE FFFIS for GSM-R SIM
cards invented yet a new way of encoding data in SIM card files: The
first record of a file may be encoded differently than further records
of files.
Let's add the required infrastructure to pySim so that the encode and
decode methods for record-oriented files get passed in the current
record number.

While in the pySim-shell, it's useful to filter the currently selected
file from the choice of available files for select, this doesn't apply
for the tracing case: It's perfectly valid for the UE to SELECT the
file that's already selected right now. The operation basically
becomes equivalent to a STATUS.

We need to pass the 'PARENT' flag to get_selectables() to be able
to track SELECT on any of the parent/ancestor DF FID.

In order to be able to explicitly select the MF via 3f00,
we need to pass the 'MF' to get_selectables(), so the record
is included in the list of selectable files from the current
working directory.

If the modem/UE doesn't ask for the FCP to be returned, a SELECT
can exit with 9000 and no response body. Don't crash in that case.

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.
