When personalizing e.g. the ICCID, the input_value is the raw
incrementing counter. From that, we calculate the Luhn check digit,
and that "output" value is what we'll put in to the EF.ICCID specific
encoder.
However, we also store that output value in the instance in order
to generate the output CSV file containig the card-specific
personalization data.
