pySim/euicc: fix encoding/decoding of Iccid

Browse Source 
The class Iccid uses a BcdAdapter to encoded/decode the ICCID. This
works fine for ICCIDs that have an even (20) number of digits. In case
the digit count is odd (19), the ICCID the last digit requires padding.

Let's switch to PaddedBcdAdapter for encoding/decoding, to ensure that
odd-length ICCIDs are padded automatically.
