Implements a PLL which locks to the input frequency and outputs a carrier
Input stream 0: complex Output stream 0: complex.
This PLL locks onto a [possibly noisy] reference carrier on the input and outputs a clean version which is phase and frequency aligned to it.
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.
