avfilter/vf_mpdecimate: debug logging of threshold stats It's often really helpful to know why a frame wasn't decimated (lo or hi), and how much you exceeded the threshold by, if you're trying to tweak the thresholds to get what you want. mpdecimate already prints a line per input frame with -v debug, this just makes it longer.
