Describe the outcome that is desired.

The DGSReduction manual test runs through a TOFTOF reduction workflow in the GUI but this could (and to some extent) already has been automated by a system test.

Specifically, TOFTOFGUITest already tests the underlying class (TOFTOFScriptElement) but with a single datafile rather than the full set of MLZ sample data, and as such does not test the numerical values of the resulting reduced workspaces.

Describe any solutions you are considering

We can either just remove the manual test and rely on the existing TOFTOFGUITest, or we can extend that test to use the full set of data and add verification of the results workspaces.

Need additional input from MLZ and core team.

Additional context

Worked as part of dev meeting code camp with @RabiyaF @mducle
Got ok from @koshchii - will modify current TOFTOFGUITest to use full data and verify results.
