Enlighten CSV loader is broken in 4.0.x

[samiebee43]

This error is independent of the CSV file itself. It looks like MeasurementFactory referencees a new field called 'view' but Measurement has not got the memo to include such a field

Context: probably broke in 4.x when we renamed the old "Technique" menu to "View." "Technique" is still the correct name for the field in saved files, so that should be switched back in MeasurementFactory.

ENLIGHTEN <4.x had a single menu in which genuine spectroscopic techniques like Raman, Transmission/Reflectance, Absorbance etc were weirdly intermixed with GUI features more appropriately named "Views" like Scope and Hardware.

Separating those into two different comboBoxes in 4.x was the right decision; it looks like we went a little overboard with a batch rename in this case.
