Change spectral rendering range from 400nm-700nm to CIE recommendation, 380nm-780nm #1415

Actually, the recommended range according to ASTM E308–15 - Standard Practice for Computing the Colors of Objects by Using the CIE System, is 360-780nm. See also https://github.com/colour-science/colour/issues/242

I did some fits with data outside this range, but there is a recommended practice when the data is available on smaller wavelength ranges than 360-780nm. We'll be using the official recommended practice.
