[GP-1111] mPower R. Apr 2021: +CEMODE shall be set to CEMODE=2
Fixed the `CellularRadio::getCarrier` implementation to use MCC/MNC
combination from the SIM intead of the serving cell.
Historically the implementation used MCC/MNC data from the cell that
is currently serving the device and provides the registration. This
MCC/MNC code is different from those of the home network in case of
a roaming - the network/carrier that provided the SIM is different
from the one who serves the device at the moment.
The more correct way to determine home carrier for GSM/UMTS/LTE devices
is to read first 5 or 6 digits of the SIM IMSI than encode the carrier.
This commit updates the implementation to use SIM IMSI as a source of
truth for the home network/carrier code.
