Export current spectrum as jcamp if 1D

[lpatiny]

If there is one spectrum selected and it is a 1D there could be one more export possibility:

Export current spectrum as JCAMP-DX

There is more or less a good example here but we should take care if it is a FID or a FT file.

@hamed-musallam Could you try to implement this ?

This will require as dependency convert-to-jcamp

It will use: from1DNMRVariables

Do you think it's more intuitive than right click -> export as jcamp directly in the list?

[lpatiny]

I was thinking about it. Maybe we could allow both.

Or it is easier to implement we can only have the export as JCAMP-DX with right click on the spectrum
