sysmoISIM-SJA2: Add support for programming IMS private user identity

Browse Source 
This EF contains the private user identity of the user. EF.IMPI consist of
NAI TLV data object values see IETF RFC 2486. The NAI shall be encoded to
an octet string according to UTF-8 encoding rules as specified in IETF RFC 3629
