[Ifeffit] Larch version up problem

[정은석]

Hello  Matt.

I think that you need some time to fix the 'multi-processing problem of 0.
9.74'. If you take a little long time to fix it, can you send me xraylarch
version 0.9.71? or could you inform me of the site of the old version?
I will reinstall xraylarch with it.

Thank you for your effort and contribution
