When the profile does not define any ADFs, then do not try to read any
AIDs. This is the case for old non UICC SIMs for example.

There are some problems with the usage of decode_select_response. At the
moment the ADF files overload the related method to provide decoding of
the select responses as per 3gpp TS 102 221. However, this also means
that the decoder is only available under ADF.USIM and ADF.ISIM. DF.GSM
and DF.TELECOM also overload the decoder method, just like an ADF would
do. This decoding method is then implemented as per 3gpp TS 51 011.
Since this a a problem on UICCs, the method detects the magic byte 0x62
that can be found at the beginning on every select response of an UICC
to defer to the TS 102 221 decoding method. TS 51 011 defines the first
two bytes of the select response as RFU. This at least problematic.
To solve this there should be a default method for
decode_select_response in the profile, which can be used if no file
overloads it with a specific decoder. ADFs use specific decoders, but
everything else should use the default decoder. When we deal with an
UICC, we expect the select response to be consistantly conform to TS
102 221, if we deal with a clasic sim we expect responses as per TS 51
011 only.
Since it is still possible to replace the select response decoder we
still have the opportunity to have custom select response in cartain
DFs and ADFs should we need them.

When pySim-shell is exited using CTRL+D it does not print a newline.
This means that the prompt of the OS shell shows up after the
pySim-shell prompt. This is irretating. Lets print a new line on exit
with CTRL+D so that everything looks straight.

The transport layer provides a method send_apdu_checksw to send APDUs
and to be sure the SW is the expected one. Given that, there is no need
to verify the SW manually. The exception of send_apdu_checksw will catch
the problem and also display the SW in a human readable form.

Currently we call the reset_card and get_atr methods directly at the
transport layer via the private _scc and _tp object of the card. This is
a violation. Fix and use the reset methods that are already in the
SimCard object.

There are situations where it is necessary to modify the class byte and
the selection control bytes of a card at runtime. This should not be
done by accessing the properties of the _scc object directly. The
modification of those properties should be done via a set method
instead.

We cannot simply skip anything that has 0xFF as first byte to detect
the padding after the end of a TLV object:
0xFF may very well be a valid first octet of a multi-octet TAG:
Tags of private class (11) with constructed (1) payload will have 0xFF
as first octet.
So let's expand the check to only detect padding in case of either only
a single byte FF being left, or two FF following each other [with
whatever suffix].

When calling from_dict() on a hierarchy of nested BER_TLV_IE,
only the first/outer layer of TLV_IE_Collection would get its
'decoded' initialized correctly from the dict. Subsequent layers
were not, as the 'decoded=' was passed as parameter during instance
initialization. If we first instantiate the class and then call the
from_dict() method, the recursive initialization down the full hierarchy
works as expected.

There are instances where a TLV IE is used as just a flag, i.e.
length zero and no value part. In those situations, it would require
a lot of boilerplate code to require the TLV_IE class definitions to
have _to_bytes/_from_bytes methods that do nothing.
So instead, add a shortcut: If we want to encode 'None', then return
b'', and if we want to decode b'' return None.

In change Id410489841bb9020ddbf74de9114d808b1d5adb6, the RuntimeState
class automatically adds additional files to the CardApplications for
ISIM and USIM. This works only once. The second time an exception will
be thrown because the added files are already in the CardApplication.
Currently there is no way generate new card applications during
initialization because the card applications are just objects that are
created once in ts_31_10x.py. Lets turn them into classes and create the
objects during initialization. This way we get fresh objects when we
re-initialize.

Currently a card must be present in the reader until the user can enter
pySim-shell. Removing and plugging another card is in theory already
possible, but then the new card will operate on the old card and runtime
state object. It might also be useful to enter pySim-shell before the
card is plugged to execute some other commands for preperation before.
So lets allow to "equip" pySim-shell with a card and rs object at
runtime.

In Icc240d5c8c04198640eb118565ea99f10ba27466 we introduced support for
writing files > 255 bytes by splitting the write into multiple chunks.
However, at the same time, that commit broke support for writing data at
non-zero offsets. Unfortunately, this is used extensively within
pySim-prog e.g. for writing K + OP/OPc data to sysmoISIM-SJA2 and sysmoUSIM-SJS1
cards.
This commit fixes the related problem.
