  23 This script uses the Proxmark3 implementations of simulation to bruteforce given ranges of id.
  24 It uses both LF and HF simulations.

  26     -- Author note
  27     -- I wrote this as i was doing a PACS audit. This is far from complete, but is easily expandable.
  28     -- The idea was based on proxbrute, but i needed more options, and support for different readers.
  29     -- I dont know LUA, so I used Brian Redbeards lf_hid_bulkclone.lua script as a starting point, sorry if its kludgy.
