Multiscale will not change the size when bigger_scale_peak > smaller_scale_peak > normal_scale_peak

Looking at this part (update method), it seems the _roi.width, _roi.height, and _scale will not change to bigger scale when bigger_scale_peak > smaller_scale_peak > normal_scale_peak. (I removed the scale_weight multiplication in this explanation to keep it simple)

Because the variables are first divided by scale_step here then multiplied with the same scale_step here. In the end, the variables return to normal scale in this case, while it should be bigger scale.
