Fix will reset the consec_zero_mv map on non-skipped blocks with non-zero mv.
Adjust thresholds on consec_zero_mv in noise estimation and skin detection,
as more possible reset on map means lower thresholds should be used.

-use larger threshold on y (as in vp8).
-add distance threshold for each cluster
-use larger skin distance threshold for first cluster
-add some early exist checks.
Keep default setting to model=0.

Use multiple clusters instead of one and decrease
the distance thresholds.
Add a define to switch between models.
Default is set to existing (1 cluster) model.

Add function to compute skin map for a given block, as its
used in several places (cyclic refresh, noise estimation, and denoising).

Simple skin detection, from vp8; works reasonable on most of the
RTC clips, but could miss sometimes.
Added debug flag to write out skin map over source input.
