The EF.AD class only had a partial decoder and no encoder before this
patch.
You can now do things like
pySIM-shell (MF/ADF.USIM/EF.AD)> read_binary_decoded
{
"ms_operation_mode": "normal_and_specific_facilities",
"specific_facilities": {
"ofm": false
},
"len_of_mnc_in_imsi": 2
}
pySIM-shell (MF/ADF.USIM/EF.AD)> update_binary_decoded '{"ms_operation_mode": "normal_and_specific_facilities", "specific_facilities": {"ofm": false}, "len_of_mnc_in_imsi": 3}'
not quite all that elegant yet, but working at all.

As we can notice during 'export': Some files had been defined
as LinFixed but are Transparent - and vice versa. Let's fix those
an bring our definitions in sync with the specs.

This commit fixes two problems (found by semgrep):
* "'foo' and 'bar' in list" is incorrect, because it's interpreted
as "'foo' and ('bar' in list)". Strings with a non-zero length
evaluate to True, thus it's True if at least 'bar' is present.
* Copy-pasted 'E-UTRAN NB-S1' checked two times.
The first condition is redundant, and the whole block can be
re-implemented using two independent 'if' statements.

pySim-prog was nice when there were only 5 parameters on a SIM that we
could program, and where the use case was pretty limited. Today, we
have SIM/USIM/ISIM cards with hundreds of files and even more parameters
to program. We cannot add a command line argument for each file to
pySim-prog.
Instead, this introduces an interactive command-line shell / REPL,
in which one can navigate the file system of the card, read and update
files both in raw format and in decoded/parsed format.
The idea is primarily inspired by Henryk Ploatz' venerable
cyberflex-shell, but implemented on a more modern basis using
the cmd2 python module.

Most code by Harald Welte. Some bug fixes by Philipp Maier
have been squashed.

the EF files in the USIM ADF are different to the ones int the GSM dir
so added the dictionary to avoid conflicts and hardcoded values
the 'DIR' one was added in ts_51_011.py, not sure if it should be there
as it's not in that standard, but did it for simplicity

This commit introduces a lookup table which maps SIM Service Number to its description.
The mapping is defined in 3GPP TS 51.011 version 4.15.0 Release 4, 10.3.7 EF.SST (SIM Service Table)

pySim has been using magic numbers to access various files which makes it hard
to read, maintain and extend. With this file in place we can start replacing all
those magic numbers with human readable names lile EF['IMSI'] instead of
['3F00', '7F20', '6F07'].
