speedup 'hf mf chk' (#901)
* add separate timeout for tag response to nr_ar * measure response time and use it for response timeout * don't drop field between keyblocks * some reformatting * some whitespace fixes * fishing for microseconds in TransmitFor14443a() * allow arbitrary number of keys in MifareChkKeys() * and move progress printing to MifareChkKeys() Co-authored-by: uzlonewolf <github_com@hacker-nin.com>
