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.
