Add produce_eko_photon to evolven3fit_new

PR for adding produce_eko_photon in evolven3fit_new

It looks ok but please instead of branching in construct_eko_cards, just make another function for the photon. At the end in construct_eko_cards you are doing a lot of different things so it is probably better to have another function. All the things that instead are in common you can put in yet another function to be called in both cases.

Actually the branching produce_eko_photon happens only in three points. I did it like this exactly because there were common blocks of code that I had to copy paste, and I didn't want to add a lot of functions for those blocks

I agree with @andreab1997 I think it is better to have different functions (and then lift some of the common functionality to wrappers) rather than so many branches.

@andreab1997 @scarlehoff Now I have separated the functions construct_eko_cards and construct_eko_photon_cards moving some code in new functions in order not to repeat some common blocks.
Tell me if you want more changes

Good for me!
