[Ifeffit] found some issues found in larch (read-in issues)

[Mauro ROVEZZI]

Dear Stefan,

Thanks for reporting these issues. Some of them are already known to us, 
but require time for fixing and implementing new features.

I take the occasion to say that anybody with Python programming skills 
is welcome to contribute and help with the development of Larch. Having 
a community of developers instead of always asking to one single person 
should be strongly considered.

Going back to your specific questions, here my two cents contribution.

These are related to:

Furthermore, with respect to an ASCII file, a Spec file may contain 
multiple scans, so it is impossible to know in advance which scan to 
select if one selects multiple Spec files to load.

To my opinion, when you need to read multiple data from many files, the 
simplest approach is to write a small python script (or Jupyter 
notebook) that reads the data and save them in an Athena project file or 
Larch session that you can then easily read back with xas_viewer.

I can further help with that.

> 3. Trouble, that I sometimes can’t unmount network volumes after reading from them, larch saved on local discs. MacOS claims that python has files open; no other python program running

I let Matt or somebody else reply on this point.

> 4. unable to save the data of one XAS-viewer while having two xas-viewer open.
