Initial support for GlobalPlatform

One can now select the Issuer Security Domain (hard-coded to
a000000003000000) and issue get_data requests.  FCI and other TLV
objects are dcoded, e.g.

pySIM-shell (MF)> select ADF.ISD
{
    "application_id": "a000000003000000",
    "proprietary_data": {
        "maximum_length_of_data_field_in_command_message": 255
    }
}
pySIM-shell (MF/ADF.ISD)> get_data CardData
{
    "card_data": [
        {
            "card_recognition_data": [
                {
                    "object_identifier": "2a864886fc6b01"
                },
                {
                    "card_management_type_and_version": [
                        {
                            "object_identifier": "2a864886fc6b02020101"
                        }
                    ]
                },
                {
                    "card_identification_scheme": [
                        {
                            "object_identifier": "2a864886fc6b03"
                        }
                    ]
                },
                {
                    "secure_channel_protocol_of_isd": [
                        {
                            "object_identifier": "2a864886fc6b040215"
                        }
                    ]
                }
            ]
        }
    ]
}
