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

[Mangold, Stefan (IPS)]

Dear All, dear Matt,

all tests were done on Macs (one M1 & one Intel) with the latest version your software & latest OS. 

1. Read-In of spec files works, but only one file at once. Even if multiple files are selected

2. If one tries to load text-files it is possible to load data form multiple files as long as you don’t try to load also the reference spectra. If you load the reference  also the read-in stopps at the transmission/fluorescence spectrum of the second file selected.

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 

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

best regards
