chg: 'lf samyrun' standalone - rework of LED messages.

Browse source 
A = bank A reading
B = bank B reading
A,C = bank A simulating
A,D = bank A cloning
B,C = bank B simulating
B,D = bank B cloning

One button press to go between steps.   Maybe practice with the proxmark3 device connected with usb-cable to see the new steps.
