Implements a PLL which locks to the input frequency and outputs an estimate of that frequency. Useful for FM Demod.
input: stream of complex; output: stream of floats.
This PLL locks onto a [possibly noisy] reference carrier on the input and outputs an estimate of that frequency in radians per sample. All settings max_freq and min_freq are in terms of radians per sample, NOT HERTZ. The loop bandwidth determins the lock range and should be set around pi/200 -- 2pi/100.
