- 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)
### Fixed
- 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)
