re: #28415

Removes all of the from __future__ imports that open and close the
brackets on the same line. This is most of them.

Also updated class_maker.py

This commit adds system tests for the new fourier filter in powder polaris.

re: 27773

re #27554

This commit add the option for the user to set the PDF output type on the polaris
create_total_scattering_pdf function. They can use any of the types available through
PDFFourierTransform (G(r), g(r), RDF(r)), if none given it will default to G(r).

Re #27607

This commit changes the value of the output of TotalScatteringMergedTest. The output value was changed by commit 6ca379 that changed how the pdf was calculated.

re #23488

The total scattering system test was made to read its own input file
instead of using the output of the focus test, so that the focus reference
file could be updated without breaking the total scattering test

The new cropping ranges meant that the intensity of peaks in
TotalScatteringTest was reduced, and the peak used for reference was at a
different index. It was decided that, since total scattering is at such
an early stage of development, it made most sense to just make the test
check for the new values instead

* Another test case must be added to ensure this can be done by looking at a saved file in the output directory

The changes to make suffix more general mean that it can't be tested from
POLARIS unit tests any more, so a suffix has been added to the POLARIS
unit test as well
