dotCooCoo 7756b1c815 Image Trace: quantize runs its passes over every pixel on all cores ...

Finding the blend pixels and settling them onto a side took about 85% of
color quantize on a 16 MP raster, all of it on one thread. The k-means
palette step works on at most 32,768 histogram bins and took under 1%.

- own_colours_among and settled work through bands of about 65,536
  pixels with layers::parallel_map (one thread on wasm32) and join the
  results in row order. settled reads every pixel's neighbors from the
  labels as they were before any change, as before, without copying
  them.
- settled_wide settles groups of its 7-column strips apart; each strip
  already started from empty buffers.
- A picture with no pixels returns before any band or strip is made.

The output does not change.
