Change label and def of VIBSO:0000007 (number of scans) to "number of accumulations"

Closes #30

@Zack-83, as you seem to have mentioned in #30 (comment), I would rather just change the label and adjust the textual definition of VIBSO_0000007 instead of minting a new term, as this was what what actually meant from my side behind this term.

[Zack-83]

Fine for me. The numbers 00000xx are in fact arbitrary, until we publish :)

[StroemPhi]

@Zack-83 & @RainerStosch if you two are now fine with the definition:
A setting datum that specifies the desired number of measurements a spectrometer has to perform to produce an usable spectrum. then we can merge.

[StroemPhi]

But please let me do the merge.

[Zack-83]

Fine for me.

[StroemPhi]

Argh. I just saw that yo9ur (@Zack-83) edited the issue description, in which the textual definition is now:
The number of acquisitions on the same location, without position change. (Relevant to improve the S/N ratio.)
If you want me to adjust the one I have now, to reflect this please let me know and I will do it later today or tomorrow morning.

[Zack-83]

Your definition sounds more general. Ours is possibly more precise. Feel free to find a suitable compromise :)
