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

This EF contains one or more records, with each record able
to hold a public SIP Identity (SIP URI) of the user. EF.IMPU consist of URI TLV data
object values see IETF RFC 3261. The URI shall be encoded to an octet string according
to UTF-8 encoding rules as specified in IETF RFC 3629
