Thomas Kolb cd9784efb6 Added frequency estimator blocks
- correct_frequency: Correct frequency by averaging the phase drift on
                     the preamble
- freq_est_lr: Luise & Reggiannini frequency estimator
- pid_controller: a PID controller that takes error values at the input
                  and generates steering values at the output

The combination of freq_est_lr and PID controller can be used together
with an NCO (signal source) to create a closed control loop for
frequency offset compensation.
