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

Adding an ability to set UE mode of operation to libmts-io.

There was added two clear virtual methods in iCellularRadio,
correct implementation for them for Telit LTE modems and implementation
with error messages for all other.
