save f1 benchmark as well, allow plotting of f1 in plot benchmarks

[WilsonGregory]

Changes

• review on ignore spacing changes for less changes in the test_plots file
• save f1 results in the benchmark function
• allow specifying 'f1' in the plot benchmarks function
• I saw how you did it with the model_variances function. I think saving all the results like that in separate and then using that function could be good, but it makes so many save files that transporting them back through ssh like I have been doing recently would be a pain. So I will keep consolidating it in 1 file like I am doing for now, I think.
• add to the unit tests

Testing

• unit tests
• ran through a script, then printed the results for accuracy and f1

Doc Changes
