[GP-1111] mPower R. Apr 2021: +CEMODE shall be set to CEMODE=2

Added an ability to read the PLMN ID (MCC/MNC combination) of the home
carrier from the SIM.

SIM PLMN ID is a part of the IMSI that contains identifier of the home
network. PLMN ID in turn consists of 3-digit MCC (country code) and
2-or-3-digit MNC (network code). The length of the MNC is stored in the
SIM Elementary File called "Administrative Data" (EFad for short).

The purpose of the new functions is to extract PLMN ID from the SIM
if this information is available.
