Package: spectra2rgb 0.1.0

spectra2rgb: Convert Spectral Signatures to sRGB and CIELAB Colour Coordinates

Converts hyperspectral reflectance signatures to device- independent sRGB hex codes and CIE L*a*b* coordinates using the CIE 1931 2-degree standard observer and the D65 standard illuminant. Includes bundled reference data so the package is self-contained. Handles missing and non-finite reflectance values via a configurable policy.
