calling external JSON cross section file.

[rajeshatiitm]

Hi Adam,

I prepared a JSON cross section file containing only Fe and Sn (for my studied compound) for the CuKalpha energy from the Yeh, et al. https://doi.org/10.1016/0092-640X(85)90016-6.

I know there is a complete list (cross_sections_haxpes.json) can be found in https://github.com/SMTG-Bham/galore/tree/master/galore/data, but I wanted to have it only for Fe and Sn. This is just a test of handeling external JSON file.

Where should I place it and how can I call JSON cross section file in the command?

Thanks, Rajesh
