* [Core] Fix#15558: Direct expression in ternary operator
* [Core] Added tests for Non-Numeric conditions in ternary op.
* [Core] prevent relational operator chains at grammar level.
* [Core] Rewrite expressions grammar as a layered grammar.
* [Core] Revert to left associative relops (like C/C++) plus tests.
* [Core] Add Boolean Functions to expressions (AND, OR, BOOL, NOT)
* [Core] Add `if` function to expressions to overcome ternary operator limitations
* [Core] Update expressions grammar to recognize relational operations as arguments
* [Core] The `if` function has been removed as no consensus was reached regarding its convenience or necessity. Its inclusion was considered potentially confusing or redundant.
* [Core] Make boolean cast based on Confusion threshold.

With the example file of issue 20299 the parser stops with an exception
and reads in the formulas only partially. This PR doesn't fix the issue
but avoids to raise an exception so that as much as possible will be
read in. For unsupported formulas a suitable message is printed with
the content of the cell.
for the specs of the XLSX file format see:
https://jkp-ads.com/articles/excel2007fileformat00.aspx or
https://www.data2type.de/xml-xslt-xslfo/spreadsheetml/xlsx-format
In order to find the correct sheet file one has to first read-in
xl/_rels/workbook.xml.rels and save the relations of Id and Target.
The file xl/workbook.xml contains a list of sheet elements where for
each element the attribute 'r:id' is set. This attribute can be used
to look up for the actual data file.
This fixes issue 19757
With PR 16130 the zooming capability was added to spreadsheet view.
The SheetTableView is added to a QGraphicsScene of a QGraphicsView
that provides the method scale(). However, this causes some problems
with header of the table view and makes resizing columns or rows
very unintuitive.
A correctly working table view is probably more important than the
possibility to zoom in or out and that's why the latter will be
disabled.
This fixes issue 19863
Dimensionless quantities have all exponents equal to zero.
Such quantities are simply numbers. The associated unit is
the unit one, symbol 1, although this is rarely explicitly
written.
See chapter 2.3.3 Dimensions of quantities, The International
System of Units, 9th edition.
* Core: Introduce PDF Import-Export dialog
Currently, we only have hardcoded exporting to one pdf version, which
leads to (as in one of the below issues) to problems, such as
non-transparent layers, which are by default not supported in PDF/A-1b.
So, this patch adds an option to the user to select their preferred PDF
version by introducing new dialog under Import-Export in Preferences,
and allowing to update that version before exporting.
* Core: Add informational messages regarding selected PDF format
* Gui: Handle Qt < 6.8 unsupported PDF format
* Gui: Switch PDF export prefs dialog to use tr()
* Gui: Remove center alignment of PDF version description
