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
First try att merging with head
Fixed compilation issues, but functionality not tested
Some minor changes and some documentation
Some more docs, also made lf hid fskdemod a bit more stable. Should be no more false readings now
