Some of the USIM-Card programming implementations do not need to look
at card responses, which means they also do not have to parse TLV
data. Lets depend on pytlv only in cases where TLV data has to be
parsed so that useser of cards that do not need at can go without
installing pytlv.

Some of the methods SimCardCommands() have ways to determaine length
information from the card response. Regular sims use a format where
the length field is on a fixed position. USIMs use FCP templates
(format control parameters), which is a TLV encodecs string. So lets
distingish if we deal with an USIM (We can easily do this by looking
at the select control parameters) and extract the length info from
the FCP.
- If we deal with USIMs, use the FCP to determine length
information

sysmo-usim-sjs1 requires P2 to be set to 0x0C (request FCI) when
using the USIM application commands. The FCI is not used by pysim
anyway and might even cause problems with other cards.
This commit adds a pair of get/set methods to the SimCardCommands
class in order to set a default for the selection control
parameters (P1, P2). (Similar to the set/get methods for the class
byte)
The SysmoUSIMSJS1 class now calls the setter method for the
selection control parameters inside of its constructuor and sets
the selection control parameter default to "000C". This way we
can be sure that we only change the behaviour for sysmo-usim-sjs1
and do not break support for any other cards.
