Add speed feature for gm parameter selection threshold
This controls the threshold for accepting a global motion model.
Being more selective with the warping error threshold causes the
recode loop to be triggered fewer times. We observe the following
speedups:
Speed 0: 16% speedup, no loss in quality on cam_lowres
Speed 1: 20% speedup, 0.07% loss in quality on cam_lowres
Speed 2: 37% speedup, 0.113% loss in quality on cam_lowres
