lf demod cleanup nrz clock detect fixes

slight adjustment to lf t55xx sampling code to start at the same spot
more consistently
reduce indala detection false positives
lf t55xx commands heavily tested and seem to be stable and reliable on
most modulations/bitrates (excluding Sequence Terminator configured
cards).
