[Ifeffit] XAS viewer unit detection during data reading

[Mauro ROVEZZI]

Dear Siebe,

In addition to the quick workaround suggested by Edmund, if you could 
send your data file to me (here or by private email), I could have a 
look why xas_viewer is not detecting the energy scale automatically.

@Edmund, usually the "xas" file type is setted automatically when the 
x-axis is identified as energy scale in the `read_ascii` function. If 
you have data files that are not detected correctly as XAS data files, 
please, do not hesitate to send them to us.

Best,
Mauro
