iceman1001 0de8e3874d A lot of changes...
.. ntag simulation stuff from @marshmellows branch "ntag/sim"
.. hf mf mifare fixes from @pwpivi.
.. hw status command
.. speedtest function from @pwpivi
.. Viking Functionalities,   (not a proper DEMOD, but a start)
.. GetCountUS  better precision from @pwpivi
.. bin2hex,  hex2bin  from @holiman

...
starting with getting the T55x7 CONFIGURATION_BLOCK for different clone situations. Ripped from Adam Lauries RFidler,   nothing working or finished..
...
Started working with the T55x7 read command with password actually performs a write block...  See Issue #136  https://github.com/Proxmark/proxmark3/issues/136    Not solved yet.
