pySim-shell: Add support for GSM-R SIM Cards with DF.EIRENE
GSM-R SIM cards have an additional directory (DF.EIRENE) with a number of files. This is all specified in the following document: UIC Reference P38 T 9001 5.0 "FFFIS for GSM-R SIM Cards" Change-Id: I4034d09292a08d277d4abcbed9a0ec2808daaacb
