Implement UICC TVL Data decoding.

Some phones / SIMs returns data in TLV format as decribed in ETSI TS 102 221 11.1.1
This enables parsing of TLV data if it finds one. This fixes reading of SIM_IO
data like ICCID, MSISDN, etc on affected SIMs.

In CM-12 this is needed for phone to function properly. In CM-12 Multisim support
requires ICCID. If ICCID is not found then user is unable to make any outgoing
calls. User is shown "Call not sent" error.
