Extend metamerism index with spectral correction.

[lassefschmidt]

Summary

This PR extends previous metamerism implementation (#1374) with spectral correction. One day late for 0.47 release 😵

To achieve this, we need to compute a matrix that contains all integration weights when integrating sd to XYZ. As we are already doing this in function sd_to_XYZ_integration, I was able to extract the relevant part into a new helper function which sd_to_XYZ_integration is now using (same math but slightly different formulation, see image).

(for notation, e.g. R x S means element-wise multiplication, NOT dot product / matrix multiplication)
