ts_102_221: Handle nested security condition data objects

ISO 7816-4 Section 5.4.3.2 "Expanded Format" permits for nesting
of security conditions using boolean operators OR, AND, NOT.

Let's implement decoding and encoding of these.

An example decoded looks like:

pySIM-shell (MF/EF.ARR)> read_record_decoded 1
[
    [
        {
            "access_mode": [
                "activate_file_or_record",
                "deactivate_file_or_record",
                "update_erase"
            ]
        },
        {
            "or": [
                {
                    "control_reference_template": "ADM1"
                },
                {
                    "control_reference_template": "ADM2"
                }
            ]
        }
    ],
    [
        {
            "access_mode": [
                "read_search_compare"
            ]
        },
        {
            "always": null
        }
    ]
]

Prior to this patch, pySim would raise "ValueError: Unknown Tag 0xa0 in bytearray"
