NMReData export currently not working

@hamed-musallam Could you check why the export is not working ?

In the meantime we could remove the button if it does not work.

It took me a while to figure out which commit removed the code. I finally found it. It was removed in a very old version, 0.31.0. @jobo322, can you remind me why you removed it? As I remember, it was not working well at that time.
