The SAIP data format is inherently flat and doesn't intrinsically
have an idea of the tree-like structure of a filesystem. However,
if we want to (for example) convert a physical USIM into an eSIM
profile, we need to find the template for a given file, where the file
is identified by its path.
Let's expose a path property of the FileTemplate object, and populate
that when creating the FileTemplate as part of a ProfileTemplate.

We previously only permitted this for transparent files (TR), but
file size can of course also be specified for BER-TLV files.

So far we only had the EF.ICCID and EF.PL within our UICC card profile.
However, a classic GSM SIM card is not an UICC, so the CardProfileSIM
also needs those files.
To avoid circular dependencies, move the definitions from ts_102_221.py
to ts_51_011.py

The existing logic is wrong. How we call from_dict() doesn't differ if
a member IE itself contains a nested collection: We always must pass a
single-entry dict with the snak-case name of the class to from_dict().

Historically, to_dict and from_dict were not symmetric; this has been
fixed in I07e4feb3800b420d8be7aae8911f828f1da9dab8 in December 2023.
This however broke the ara_m legacy use of the from_dict() methods.
We've just introduced a from_val_dict() method in
I81654ea54aed9e598943f41a26a57dcc3a7f10c2, let's make use of it.

We put those in ts_102_221 because that's where ProprietaryInformation

This fixes a long-standing bug in the FileDescriptor IE class which so
far only supported decoding, but not encoding of BER-TLV file
descriptors.

This command exports the entire filesystem state as one JSON document,
which can be useful for storing it in a noSQL database, or for doing a
structured diff between different such dumps.
It's similar to "export", but then reasonably different to rectify a
separate command.

There are some situations where we want to work with a type-name-wrapped
dict that includes the type information, and others where we don't want
that. The main reason is that nested IEs can only be reconstructed if
we can determine the type/class of the nested IE from the dict data.
Let's explicitly offer {to,from}_val_dict() methods that work with
the value-part only

In the read and write command implementations, we used to catch
lower-layer exceptions (usually SwMatchError) and "translate" that into
a value error, only to add more information to the exception. This
meant that higher-layer code could no longer detect this was actually
a SwMatchError exception type.
Let's instead use the add_note() method to amend the existing exception,
rather than raising a new one of different type.

The new methods allow programmatic resolution of nested IEs from
a parent, assuming there's only one child of a given type (which is
often but not always the case).

The reset command resets the card using the card object. This unfortunately
leaves the RuntimeState uninformed about the event. However, the RuntimeState
class also has a reset method that resets the card and the RuntimeState. Let's
use this reset method. Also fix this method so that it ensures that the SCP is
also no longer present.

When we traverse the file system using the command "export" we will
also select all ADFs but not all ADFs may have UICC file system support.
This makes it impossible to exit those ADFs again. To exit anyway we
select an application with filesystem support first and then the parent
EF we wanted to select originally. This method may not only be useful
when traversing the filesystem, so let's put it into the RuntimeLchan
class and change it a little so that it would also work if the ADF in
question is an a sub DF.

The code that generates the filesystem export lines for the various
different file structures can be moved into the filesystem class model.
This simplifies the code since we do not need any extra logic to
distinguish between the different file structures.

In the past, we always wrapped a HexAdapter around bytes-like data in
order to make sure it's printed as hex-digits. However, now that we are
doing JSON output it's much easier to let the pySim.utils.JsonEncoder
take care of this in a generic way.
We should do a similar migration all over pySim (pySim-shell,
filesystem, etc.) - but for now only do it in the low-hanging fruit of
pySim-trace aka pySim.apdu

Let's factor out the "automatic processing using _tlv / _construct" as a
separate method. This way we enable a derived class to first call that
automatic processing method, and then amend its output in a second step.

Versoin 1.2". Specifically, this patch covers the TLV definitions for
