  Add frequency correction support. The drift factor is currently
  determined via linear regression of the last 8 offset corrections.
  It is bound to 128 ppm in one step to avoid extreme drifts when
  the drift calculation is incorrect for some reason. With the
  default values this can result in a maximum wrong drift of
  8 * 60 * 8 * 128e-6 s ~= 0.5s (samples per update, update interval,
  samples to trigger drift correction, max. drift error) until the
  next iteration is done.
