* \brief IQ balance utils implementation

* The actual algorithm used for estimation of the imbalance and its
* optimization is inspired by the IQ balancer of SDR# by Youssef Touil
* and described here :
*
* http://sdrsharp.com/index.php/automatic-iq-correction-algorithm
*
* The main differences are:
* - Objective function uses complex correlation of left/right side of FFT
* - Optimization based on steepest gradient with dynamic step size
