Add Ability to Load Existing Calibration into Engineering Diffraction UI

Add normalisation by bin width for 2d plots in workbench

Before, the setEnabled method was written into the MWRunfiles class
instead of simply using the one that is part of Qt that disables all
sub-widgets anyway.

Fix crash when opening script with syntax error

Move axis functions from curves tab widget presenter to figure errors manager

Attach muon plotting to GUI

Fix test failure on RHEL 7 when not using UTC timezone

When opening a script with an import (including the default ones) and a syntax error it caused a crash.
This occured due to the code completion failing to parse the import
An extra check has been added to avoid the crash

If the test is run in an environment not using the UTC timezone, then
the test could fail due to a the conversions to the C++ DateAndTime
followed by numpy printing the result in the local timezone. This was
only occuring on machines running an ealier version of numpy than 1.11
due to this change:
https://docs.scipy.org/doc/numpy/reference/arrays.datetime.html#changes-with-numpy-1-11

When normalising it is very difficult to see if the graph is normalized.
This commit changes the title to be the counts axis label used in 1d plots

Bump Minimum CMake to 3.13

Add SANS to LOQ sys tests filenames

Replace hardcoded index for MergeSpectra in polaris create_total_scattering_pdf

Add enum34 backport to RHEL rpm

Fix remaining memory leaks in C++ tests

Abins: fix compatibility with CRYSTAL17 molecular calculations

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.

A temporary vector of raw pointers is constructed
instead for passing to splitBytimeVector. It is better
to have the memory handled safely than worry about the
minor cost of this allocation.

This commit adds to the lease notes that the fix for the bug that raised an error when a unicode string was given as a lim file directory has been fixed.

This commit adds to the lease notes that the match spectra in merging workspaces no longer matches by scale.

Re #27444

This commit adds release notes for the changes made in this PR.

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

Add SANS to LOQ system test names so that -R SANS works correctly

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
