Returns a uniform nonrational B-spline interpolator through the specified array of colors, which are converted to RGB color space.
The control points are implicitly repeated such that the resulting spline has cyclical C² continuity when repeated around t in [0,1];
this is useful, for example, to create cyclical color scales. Opacity interpolation is not currently supported.
See also `d3.interpolateBasisClosed, and see d3-scale-chromatic for examples.
