This introduces a basic, low cpu-cost NF estimator which works by using an exponential moving average over the magnitude of the received signal updated only outside of ACARS message processing. The computational overhead of this extra estimator is virtually nil, as the signal power estimator has been reworked to use the same input as the noise floor estimator. Fixes: TLeconte#84

acarsdec shows the signal level of messages. If it could also show the noise floor level this would be very helpful in adjusting the SDR's gain value to yield the best signal-to-noise ratio for a user's antenna and location.
