In case try to decode the contents of an uninitalized EF.IMSI, the
function dec_imsi() would crash because it truncates all 0xFF from the
swapped version of the EF.IMSI contents and then accesses the first
element of the buffer. This always works for EF.IMSI contents that
contain valid IMSI data, but if all bytes are set to 0xFF, then no data
is left in the buffer after truncating, so lets check if we even have
bytes left before we move on with the decoding.

When writing to files we often just write without making sure that the
actual file contents actually written. Lets add features to do a
read-after-write verification when writing to files.

For record oriented files we have the methods record_size() and
record_count() to determine the dimensions of a record oriented file,
however, we miss a similar function for regular binary files. Lets add a
method binary_size() to quickly determine the size of a non record
oriented file

The lower part of gen_parameters() in pySim-prog.py contains some code
that checks whether the ADM pin supplied in its hexadecimal or in its
string form and generates a sanitised pin_adm from that. Lets separate
this part as it may become useful elsewhere too.

The contents of EF.AD me be uninitalized (all bytes set to 0xff). If
this is the case reset all bytes of the file to 0x00 and continue the
update of EF.AD with this value.

A MNC of 02 and 002 are *not* equal. The former is a two-digit MNC
and the latter is a three-digit MNC. Hence, we shouldn't treat
MNCs as integer values as we have no clue how many leading zeroes
(if any) the user entered.

Closes: OS#4523
pySim-prog and pySim-read currently echo back the pcsc reader id (or
baudrate/socket, depending on the interface used). This makes the output
unecessarly undeterministic, which becomes a problem when verifying the
putput in tests. Lets not echo those variable, user supplied parameters
back. Also lets move the code that does the initalization to utils, so
that it can be used from pySim-prog and from pySim-read (code dup).

As per TS 31.103, This EF indicates which ISIM services are available.
If a service is not indicated as available in the ISIM, the ME shall not select this service.
Parsing of IST is achieved by first selecting the ISIM application using its AID.
This is followed by selecting EF.IST with File ID - 6f07 in ADF.ISIM

When pysim-prog programms the application specific files of ISIM and
USIM it selects the application by its AID first. If depending on the
card profile one of the applications is missing the selection of the
related ADF will fail. Lets check the presence of the AID first and if
it is not present lets skip the programming of the related files.
