Update AlignAndFocusPowder to use new rebin paramters from DiffractionFocussing

[rosswhitfield]

Description of work

Use new options from DiffractionFocussing added in #38154 in AlignAndFocusPowder.

I added a unittest for ragged binning in AlignAndFocusPowder but it is also covered by existing system tests, e.g. AlignAndFocusPowderFromFilesTest.VulcanRaggedInD

Summary of work

Fixes 7072: AlignAndFocusPowder supplies DiffractionFocussing binning parameters

Further detail of work

To test:

Modifying the usage example you can play with the parameters and see the the log information shows this is running correctly.

PG3_9830_event = Load('PG3_9830_event.nxs')
out = AlignAndFocusPowder(PG3_9830_event, CalFileName='pg3_mantid_det.cal', DeltaRagged='0.1',DMin="0.5,0.35,0.3,0.28",DMax="3.5,1.3,1,0.85")

and the output log shows
