[Ifeffit] Fe K edge spectrum of scorodite

[Case Van Genuchten]

Dear Matthew,

Sure, the raw data and/or spectrum can be added to the database.  For this
sample, the 1st derivative of the Fe foil was 7.112 keV.  I can also
provide individual scans for the database, if needed.  Is there any
interest in the As K-edge of this sample, too?  I have that one as well.
