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 renames the MergeWorkspacesWithLimits algorithm to MatchAndMergeWorkspaces as it better describes the intended usage
This commit also adds tests relating to the expanded usage of the
MatchAndMergeWorkspaces algorithm

Re: #27445

This commit modifies the MergeWorkspacesWithLimits algorithm to be usable
outside of the polaris scripts. The changes to the algorithm are as follows:

- Fixing the ADSValidator export to python.
- The Algorithm can now accept a group workspace, a multi-specta workspace, or a list of workspaces.
- The Algorithm can take an input use with MatchSpectra for if the scale or offset should be calculated

Re: #27445

For thin samples the number of sample elements ends up quite high
and simulating each wavelength is unrealistic.

- Remove repeated searching checks

- Split test into reasonable chunks

- Make rb_num naming consistent

This commit corrects issues related to the changing property names in
MergeWorkspacesWithLimits and TotScatCalculateSelfScattering

re: #27445

This commit makes several changes requested during code review including:

- Rename CalculateSelfScatteringCorrection to TotScatCalculateSelfScattering
- Removing unnecessary __init__ function
- Correcting property docstring for CalFileName
- Changing CalFileName into a FileProperty

re: #27445

Vanadium output files are now saved to the user directory if an RB
number is specifies so that users can have all of the generated data
from processing.

Focusing now saves as .gss, .nxs, and .dat files.

Now using sample instead of a mix of both of these.

Before, the file finders (MWRunFiles) could only be made read-only,
which did not grey out the text field, just the browse button. This
option has been added and used instead for the file inputs that should
not be used.

Loading the vanadium to be used later on makes more sense to do at this
stage than at the start of the focusing step.

The calibration parameter table that is generated when creating a new
calibration is now loaded back into mantid from the file as a table
workspace, rather then just working in the background.

Parts of the UI that do not do anything are now greyed out to avoid
confusion. The returned values from the load are also added to the new
calibration boxes to show that the load has succeeded.

Loading an existing calibration from the GSAS parameter files now reloads the calibration from the information stored in the file.

This commit removes the _merge_workspace_with_limits function that had been
previously removed in a different commit, It was accidentally returned to the script
when the branch had to be rebased after a commit message had to be changed to
match the required level of detail and proper formatting regarding the method of
referencing git issues, that being 'Re' followed by hash then the number.

Re #27445

This commit removes the _calculate_self_scattering_correction function in
polaris_algs that is now covered by the CalculateSelfScatteringCorrection algorithm.

Re #27445

This commit creates a documentation rst file for MergeWorkspacesWithLimits
Along with the workflow diagram dot file. It also makes changes to the
MergeWorkspacesWithLimits algorithm to include a name and version that
is required by the documentation compiler.

This commit corrects a mistake in the property names for
CalcuateSelfScatteringCorrection.

This commit removes the commented out command to the
_merge_workspaces_with_limits function in polaris_algs in place of the workflow
algorithm.

This commit creates a blank rst file that will later contain the documentation for
CalculateSelfScatteringCorrection.

Re #27445

This commit creates a workflow algorithm named MergeWorkspacesWithLimits
that handles the merging of the focused workspaces in the polaris scripts.

This commit removes a duplicated _load_qlims function in polaris_algs mistakenly added in commit 4c588e.

This commit adds a black line at the end of the CalculateSelfScatteringCorrection algorithm.

Re #27445

This commit creates a workflow algorithm named CalculateSelfScatteringCorrection
that handles the calculate of the placzek self scattering correction to be subtracted
from the focused data in the polaris scripts.

Re #27445

This commit fixes missed line that would allow the index for the max range spectra
to be updated

Re #27444

This commit moves the code for reading the supplies q limits into its own function.
This also fixes a bug that cause an error when trying to read a lim file path that is in
a unicode format.

Re #27444

This commit adds a catch for if the workspaces or q_lims file have an infinite range

Re #27444

This commit fixes missed line that would allow the index for the max range spectra
to be updated

Re #27444

This commit moves the code for reading the supplies q limits into its own function.
This also fixes a bug that cause an error when trying to read a lim file path that is in
a unicode format.

Re #27444

This commit changes the previously hard coded index for matching spectra to
instead use the workspace with the larges range of x values as these produces the
smoothest match around the edges of the workspaces data.

Re #27444

This commit changes the usage of ConjoinSpectra to a loop using ConjoinWorkspace.
This is done because using ConjoinSpectra the focused workspace can have a
mismatch between specnumbers and index

Re #27444

Removes the Py3Compat shim for Enums and converts all associated callers
to use the natively provided Python version (either through a backport
or in Python 3.4 onwards)

Addresses some issues from a review where:
- A setter is incorrectly named get
- A redundant assignment is removed

Fixes multiple Python 3 compatbility issues where we were encoding into
a byte string, then attempting to use it in the conversion to string
