Major refactoring of lfops, removed a lot of duplicate code
Refactoring low frequency operations, now 'lf hid fskdemod' is more stable. Also did changes to handling ioprox tags, this is yet untested, so until it's been tested it should be kept off 'stable' branch
Implement replay command.
Updated proxmark research with Holiman's loclass framework
improved calc_iclass_mac to work independant of size
implemented 'hf iclass dump xxxx',
all you need is the magic key to dump contents of an iclass card
