fix lf search bugs when no tag is on antenna

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

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...
