These commands can be used to decode a user-provided hex-string,
instead of decoding the data read from the file. This is useful
for quickly manually decoding some values read from other locations,
such as e.g. copy+pasted from a eSIM profile in ASN.1 value notation.

The OPL has 7 bytes "LAI" as the LAI actually contains a LAC
range (so two more bytes for the end of the 16bit range).
Change-Id: I74bcf10b0a8977af0f2844044a812c5780af1706
range(0,7) in python is 0..6, and not 0..7, so we need range(0.8)
to produce the desired range covering all bits of a byte.
This resulted in services 8,16,24,... not being displayed in
the decoded output of EF.UST / EF.IST.

The SFI TLV contanins not the raw SFI, but it contains the SFI
shifted to left by 3 bits (for some strange reason). So let's
un-shift it.

* don't duplicate information between .rst files and docstrings
* if there's more than a trivial single-line documentation, put it as
docstring into the python source and use ".. argparse" to pul it into
the manual
* add documentation for some commands for which it was missing
* show one level deeper in the navigation table, listing the commands

The FCP template provides us a lot of context, like the permissions of
a given file. Let's make it part of the 'export' output, both in raw
and in decoded form.

This adds support for creating/deleting and terminating files,
as well as support for permanent card termination.

With this patch applied, users can directly enter commands like
select DF.GSM/EF.IMSI or
select ADF.USIM/DF.5GS/EF.5GAUTHKEYS
This feature doesn't have tabl completion, so it's mostly useful
for when you know what to select, or for use within scripts.
Change-Id: I681a132eb2df4b2aba4c2ccbdd21c6d5b88443e3
We must not only consider files in the current directory (ADF.USIM)
but also in its sub-directories. This requires us to be able to
determine the path we need to traverse between the currently selected
file (EF.UST) and the respective file in some other directory,
which is implemented via CardFile.build_select_path_to().
Change-Id: I61797fefa9dafa36a8a62c11aa2cfaeecb015740
We had service annotations only for ADF.USIM so far, but not for
the related sub-directories.

Note: The code doesn't make use of them in any reasonable way yet!
The existing code had the following serious problems:
* when trying to update EF.SST or EF.IST, it would write to EF.UST !
* shell commands were called ust_* even for the EST/IST files
Let's introduce the proper separation between what is shared and what
is file-specific.

This command performs a consistency check between the services activated
in EF.UST/EF.IST and the files that should (or should not) be
active/selectable for the given service.
Produces output like:
Checking service No 48 (inactive)
ERROR: File EF(EF.MWIS) is selectable but should not!
Checking service No 49 (active)
ERROR: File EF(EF.CFIS) is not selectable (SW=6a82) but should!

We want people to use pySim-shell and should not mislead them by
having usage examples of old tools in README.md. Also, all
documentation should be in the manuals, let's try to have bits
and pieces in various places.
Change-Id: I8c07a2e0778ab95fb42be6074acb80874e681d20
This allows us [in a future patch] to perform consistency checking,
whether files exist for services not activated in EF.{UST,IST} or
vice-versa: Services are activated by files are not present or
deactivated.

This can be populated by card profiles with the SST/IST/UST service
that is associated with the file.
Change-Id: I3b3f74b691368fa09967ecb377a9f7a6d8af7869
This can be useful when playing around with cards, for example
sending commands for which pySim-shell doesn't yet have proper support.

The primary use case of the --json option is to systematically execute
all of our decoder classes in order to find bugs. As we don't have
encoders for all files yet, the output generated by 'export --json'
will in many cases not be executable as script again, unlike the normal
'export' output.

pytlv is a nightmare of shortcomings, let's abandon it in favor of
our own meanwhile-created pySim.tlv. This has the added benefit
that unknown tags finally no longer raise exceptions.

Our hand-written JSON so far is using snake_case identifiers,
while the JSON generated by the pySim.tlv classes use the class
names as keys, which LooksQuiteDifferent.
So let's auto-convert the CamelCase into something that reflects
our existing notion.

We had a mixture of tab and 4space based indenting, which is a bad
idea. 4space is the standard in python, so convert all our code to
that. The result unfortuantely still shoed even more inconsistencies,
so I've decided to run autopep8 on the entire code base.

In Change-Id I6d7c1bf49a8eaf3d8e50fb12888bf3d5b46b6c55 we fixed the
filesystem code to assume the self._tlv memper is a reference to a
class, and not an instance (as this is what the majority of the code
did).
However, it seems thre wer two instances where we actually had _tlv
reference an instance. Change that to class so it's the same all over
the code base.
