Add initial suport for MIFARE Key Diversification

Browse source 
This adds two new options to `hf mfdes auth`

```
    -d, --kdf <kdf>                Key Derivation Function (KDF) (0=None, 1=AN10922)
    -i, --kdfi <kdfi>              KDF input (HEX 1-31 bytes)
```

By specifying `-d 1` and some kdf data `-i 00112233`, the key will be
diversified using AN10922.
