Tracker::proc_face_detect increases the size of the face boundary by 10% to compensate for in increased face size due to yaw, pitch and roll.
But it also needs to guaranteed a minimum amount of pixels for faces at farther distances where the boundary is much smaller.

this fixes "Losing tracking at distances approx > 2 meters (v0.6.6 and v0.7.0)" https://github.com/AIRLegend/aitrack/issues/173 Head tracking was tested at distances of 4 to 5 meters
