ColourCheckers Spectral Power Distributions

Defines ColourCheckers spectral power distributions.

Each ColourChecker data is in the form of a dict of colour.colorimetry.spectrum.SpectralPowerDistribution classes as follows:

{'name': SpectralPowerDistribution, ..., 'name': SpectralPowerDistribution}

The following ColourCheckers data is available:
