Add 'hf mf staticnonce' - a nested find all key solution command for tags that has a static nonce. \n See https://github.com/RfidResearchGroup/proxmark3/issues/133 \n See https://github.com/Proxmark/proxmark3/issues/899 \n This solution is based upon the ideas and solutions of @uzlonewolf and @xtigmh . Thanks!

## [unreleased][unreleased]
|
||||
- Added `hf mf staticnested` - useful when targeting the strange cards with a static nonce. (@iceman100) Thanks to @xtigmh @uzlonewolf for their solutions.
|
||||
- Added `hf plot` (@pwpiwi)
|
||||
- Fix `lf config` - when called with no params, it no longer mess up all device lf config settings. (@iceman1001)
|
||||
- Change `lf indala clone` - new option `--Q5` writes to q5/T5555 tags. (@iceman1001)
