sysmoISIM-SJA2: Add support for programming IMS Home Network Domain Name

Browse Source 
As per 3GPP TS 31.103, this EF (DOMAIN) can found under ADF.ISIM at File Id 6f03.

The Home Network Domain Name, i.e. FQDN shall be encoded to an octet string
according to UTF-8 encoding rules as specified in IETF RFC 3629 [27].
The tag value of the Home Network Domain Name TLV data object shall be '80'.

Example:

./pySim-prog.py -p 0 -x 001 -y 01 -s 8988211900000000004 -i 001011234567895 -k 8baf473f2f8fd09487cccbd7097c6862 --op 11111111111111111111111111111111 -o 8E27B6AF0E692E750F32667A3B14605D -a 85524953 -n isim.test --msisdn 0598765432100 --epdgid epdg.epc.mnc001.mcc001.pub.3gppnetwork.org --pcscf pcscf.testims.org --ims-hdomain testims.org
