"illuminant" and "type" attributes are not described in "JSON Schema for Spectral Datasets".

Hi,

I just noticed that the illuminant and type attributes are not described in the JSON Schema for Spectral Datasets:

• illuminant: https://github.com/ampas/rawtoaces/blob/master/data/illuminant/iso7589_stutung_380_780_5.json#L4
• type: https://github.com/ampas/rawtoaces/blob/master/data/training/training_spectral.json#L4

So we end up with the following attribute specificities:

• camera: manufacturer, model
• cmfs: type
• illuminant: illuminant
• training: type

It is not super consistent and not very generic, it is also very odd to have illuminant: illuminant and cmfs: type, should both the same a way or another for consistency.

Maybe using type for everything is the way to go?
