    ranap ASN.1: Define IMSI as OCTET STRING to work around asn1c bug
    
    When IMSI is a TBCD-STRING type, and TBCD-STRING is defined as OCTET
    STRING, we end up encoding the IMSI the wrong way.  I don't knwo why
    that is, but changing it fixed the problem, as described below:

    0a                              (length)
    00                              presence = IMSI
    08                              BUG: why the additional length field?
