filesystem: define more convenient codec for EF.ACC

Browse Source 
This patch improves the output of the 'read_binary_decoded' command:

pySIM-shell (MF/DF.GSM/EF.ACC)> read_binary_decoded
{
    "ACC0": false,
    "ACC1": false,
    "ACC2": false,
    "ACC3": false,
    "ACC4": false,
    "ACC5": false,
    "ACC6": false,
    "ACC7": false,
    "ACC8": false,
    "ACC9": false,
    "ACC10": false,
    "ACC11": false,
    "ACC12": false,
    "ACC13": false,
    "ACC14": false,
    "ACC15": true
}

And allows to set/unset individual ACCs using 'update_binary_decoded':

pySIM-shell (MF/DF.GSM/EF.ACC)> update_binary_decoded --json-path 'ACC15' 0
"0000"
pySIM-shell (MF/DF.GSM/EF.ACC)> update_binary_decoded --json-path 'ACC8' 1
"0100"
pySIM-shell (MF/DF.GSM/EF.ACC)> update_binary_decoded --json-path 'ACC0' 1
"0101"
