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.
