pySim-prog.py: add support for MSISDN programming

This change implements programming of EF.MSISDN as per 3GPP TS 31.102,
sections 4.2.26 and 4.4.2.3, excluding the following fields:

  - Alpha Identifier (currently 'FF'O * 20),
  - Capability/Configuration1 Record Identifier ('FF'O),
  - Extension1 Record Identifier ('FF'O).

This feature is introduced exclusively for sysmoUSIM-SJS1.
Othere SIM card types need to be tested.
