Create a JSON file containing spectrally resolved data

[MDKempe]

We need a JSON file containing a standard AM1.5 spectra AM0 and other spectra.

It should also include the spectra of a number of representative environmental chamber lamps. (e.g. xenon arc with varied filters, UVA fluorescent lamp, UVB fluorescent lamp, and a variety of MH lamps).

Once completed the Arrhenius function in degradation.py should be upgraded to use this to create a representative spectrum.

Does pvlib.spectrum.get_reference_spectra go any way in addressing this?

Does pvlib.spectrum.get_reference_spectra go any way in addressing this?

Yes but only in part. This would allow degradation.py to create a generic representative spectrum. But in the future I would like to be able to translate chamber spectral damage to outdoor damage. So I think I might just fix degradation.py and keep this issue as a placeholder for now. It addresses a problem that comes up a lot in degradation studies discussions.
