Both `hf mfdes auth` and `hf mfdes chk` now support Key Diversification for
AN10922 and as special treat, Gallagher issued cards.
For `hf mfdes auth`:
```
-d, --kdf <kdf> Key Derivation Function (KDF) (0=None, 1=AN10922, 2=Gallagher)
-i, --kdfi <kdfi> KDF input (HEX 1-31 bytes)
```
And for `hf mfdes chk`:
```
-f, --kdf <kdf> Key Derivation Function (KDF) (0=None, 1=AN10922, Gallagher)
-i, --kdfi <kdfi> KDF input (HEX 1-31 bytes)
```
Examples:
- `hf mfdes auth -a 2081f4 -m 3 -t 4 -d 2 -n 2 -k 00112233445566778899aabbccddeeff`
Will diversify the key for key `2` on AID `2081F4` for Gallagher issued cards
- `hf mfdes chk -f 1 -i 00112233 -d mfdes_default_keys`
Will read in all the default keys from the dictionary, and diversify them
using AN10922 with the input data `00112233`
- `hf mfdes chk -f 2 -d mfdes_default_keys`
Will read in all the default keys from the dictionary, and diversify them
using AN10922 but with input data generated from the card's UID, AID and
key number.
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.
