  1. Contour: include minimum raster value as contour line when it exactly… 

    … matches the first level

Fixes OSGeo#10167

There's currently an asymmetry since the maximum raster value is
included. This is due how the marching square thresholding compares
pixel values to the candidate contour levels. Add a special case to
modify the comparison for the level that matches the minimum raster
value.
