fix lf search bugs when no tag is on antenna

Browse source 
cotag read could enter endless loop, now cancels if the next bit doesn't

em4x05 detection would loop due to a threshold never being met, now has
a dump out after 1000 samples tested.

fixed some indenting in hitag2 while i was reviewing that code for
potential endless loops...
