Lets add test vectors for the per-record/per-file encode/decode of
our various classes for the Elementary Files.
We keep the test vectors as class variables of the respective EF-classes
to ensure implementation and test vectors are next to each other.
The test classes then iterate over all EF subclasses and execute the
decode/encode functions using the test vectors from the class variables.

This fixes a regression introduced in Change-Id
I02d6942016dd0631b21d1fd301711c13cb27962b which added support for
different encoding/decoding of records by their record number.
Change-Id: I0c5fd21a96d2344bfd9551f31030eba0769636bf
The encoder function apparently was never tested, it didn't match at all
the output of the decoder, not even in terms of the string keys of the
dict.

ValidityPeriodAdapter() must return integer values when encoding a
value, as only integer values can be expressed in the binary format.

As per EIRENE GSM-R SIM-Card FFFIS, EF_IC conatains records of 1+2+2+2
bytes, the network string table index is 16bit and not 8bit as we
implemented so far.

When decoding the SELECT response of a clasic GSM SIM without
UICC functionality, we
* did not decode the record length or number of records
* accidentially reported the EF file_size as available_memory (like DF)
Let's fix those two, and also add a comment on how the output dict
of decode_select_response() should look like.
As a result, code like 'read_records' now knows the number of records
and can iterate over them rather than raising exceptions.

This file is a optional file specified by TS 51.011, storing the last
numbers dialled. As the EIRENE FFFIS for GSM-R SIM refers to this,
we must implement it to have full GSM-R support in pySim.

We're using a shared class to implement the identical file encoding
for EF.{ADN,SDN,MBDN,BDN,FDN,CFIS}. However, they all point to
different extension files.
Previosly for EF.SDN:
"ext1_record_id": 255
Now for EF.SDN:
"ext3_record_id": 255

TS 51.011 specifies an "Extended BCD Coding" in Table 12 of Section
10.5.1. It allows to express the '*' and '#' symbols used in GSM
SS and/or USSD codes.

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.
This patch implements the feature based on the newly-introduced way by
which we pass the record number to the encoder and decoder methods.

DF.GSM and ADF.USIM have an EF.AD with nearly the same contents. Usually
there is one file physically present and the other is just a link.
Apparantly this is not always the case for sysmo-ismi-sja2 cards, so
lets program EF.AD in both locations.

The function name "write_parameters" is very generic and since it is
called during the programming cycle it should be made clear that it is
not about writing parameters to the card.

The process_card function has a dry-run mode where one can test
parameters without actually writing to the card. However, the dry-run
feature also does not perform read operations and connects to the card
reader at a different point in time. Lets be more accurate here and
perform all operations a normal programming cycle would perform but
without calling the card.program() method.

The handling of the mnclen parameter does not work. Lets fix it so that
it can be used again with CSV and normal card programming. Lets ensure
that depending on the parameter and the defaults it is always ensured
that the mnc string has the correct length so that lower layers can
deduct the length of the mnc properly by the string length of the mnc.

The decoder/encoder of that decodes the EF.xSIM_AUTH_KEY files has an
overcomplicated handling for op/and opc. There is a condition that
checks if milenage is configured and another one that checks if the
string is recognized as OP or OPc. Both is not correct and seems not to
work (op and opc is always displayed as "null")
The encoder/decoder should focus on the physical file layout and
regardless of any other conriguration the OP/OPc field is physically
present and should be displayd and presented for editing.

Argument 'signed' was added in [1] and become available since v2.10.63.
Therefore using bytes2integer() and integer2bytes() from construct.core
bumps the minimum required version of construct to v2.10.63. For
instance, debian:bullseye currently ships v2.10.58.
There is no strict requirement to use construct's API, so let's use
Python's API instead. This allows using older construct versions
from the v2.9.xx family.
