Check keys in hf mf nested and hf mf chk (#414)
Improve hf mf chk and hf mf nested * hf mf chk. added interrupt of procedure by usb * extract mifare default keys into separate module * arm side multisector `hf mf chk` * hf mf nested. change key search procedure * hf mf nested. added key check after we have found a key. * small fix hf list f * hf mf chk. add timeout (arm side) and some tweaks.

- Deleted wipe functionality from `hf mf csetuid` (Merlok)
|
||||
- Changed `hf mf nested` logic (Merlok)
|
||||
- Added `hf mf nested` mode: autosearch keys for attack (from well known keys) (Merlok)
|
||||
- `hf mf nested` Check keys after they have found (Merlok)
|
||||
- `hf mf chk` Move main cycle to arm (Merlok)

|

- Added `hf mf cwipe` command. It wipes "magic Chinese" card. For 1a generation it uses card's "wipe" command. For gen1a and gen1b it uses a write command. (Merlok)
|
||||
- Added to `hf mf nested` source key check before attack (Merlok)
|
||||
- Added to `hf mf nested` after attack it checks all found keys on non-open sectors (Merlok)
|
||||
- `hf mf chk` Added setings to set iso14443a operations timeout. default timeout set to 500us (Merlok)
