lf read adjustments

add parameter for # bits to read
auto get samples after lf read/snoop (don't need to do a `data samples`
anymore)
add safe function to get DemodBuffer
add some lf demod comments and apply new lf_read function instead of
read then get samples.
fixed output bug in lf t55xx config print
fixed small bug in lf t55xx detect during ST check
