- Refactor LoadMuonNexusV2Helper into a separate class
- Avoid passing shared pointers around if ownership is not being considered
Remove unused variable

This commit creates the multi period loading strategy
In doing this it refactors some of the code from the single period strategy, as it would end up being repeated in the Multi period loading strategy.

Check for null box pointer due to rounding errors

Some scenarios cause getBoxAtCoord to return a nullptr
due to roundoff errors. Protect against this possiblity
when generating a line plot. No test has been added as it
is nontrivial to construct a case and the functionality
fixes a crash in an edge case in MantidPlot sliceviewer
that will be removed in the next release

Update Muon loaders to load uncorrected time and multiple time zeros

Add region/cut selection tool to the slice viewer

Colour fill plots fail on workspaces of monitors

Change const to constexpr in various places and rename the SparseInstrument
header\cpp\test files to SparseWorkspace to match the class. Also remove
redundant try catch clause in MCInteractionVolume::getFullBoundingBox

Code can be the same whether the axis type is numeric/spectra
by using the correct algorithms

If an algorithm fails midway but we leave the workspace
around it looks like the operation completed causing
confusion for the user.

This commit adds checks for spectra labels being text and replaces them with arrays of length nhist

Add F(q) default parameter estimations

Add Setting for Default Font on New Plots

Modified MonteCarloAbsorptionTest.h to add more unit tests, add
integration tests that are based on scenarios with an analytic result
and remove a couple of integration tests where good system test cover
already in place
Add one more test to SpareInstrumentTest to check the inverse square
weighting

RE #28597

Muon Analysis bug fixes for simultaneous fits

Updates the LoadPSIMuonBin algorithm to set a new output property called TimeZeroList listing all the time zeros. Also adds a new flag CorrectTime controlling whether to correct the time via the time zero algorithm in the loader or not.

This adds an optional flag to disable automatically applying the timezero correction. It also adds a new property TimeZeroList which contains a vector of time zeros one for each spectra. If the file does not contain multiple time zeros this vector contains the single timezero for every entry.

Abins data class refactoring

The same key combinations, minus roi selection, now export
the visible cuts when the single-pixel line plots are
visible.

It is highly likely that this is the behaviour that is
intended rather than simply throwing an error. If makes
extracting a single bin out far simpler than a user
figuring out the correct limits themselves.

RE #28597

The toolbar was incorrectly stretched over 2
columns but only macOS show this as a layout
error.
Also, macOS buttons were sized far too small
and the text was cut off. Calculate the width
of the buttons based on their height so they
appear square

Fix macOS layout properly

Some values cannot be displayed so show a blank

Some units are not convertible so we just show a dash to
show it's not applicable.

We only want to borrow a reference to the PyObject for ExtractSharedPtr
to work. The handle objects are able to do this but providing access to
the raw PyObject in ExtractSharedPtr avoids the overhead of constructing
the handle when not required.
