IfcQuantity* carries an optional Formula (IfcLabel) documenting how a
quantity was derived. Export it alongside each quantity so it survives
in the Quantities column.
The per-quantity entry shape grows from [name, value] to
[name, value, formula], which stays backward compatible for positional
consumers reading index 0/1. Formula is read with a schema-safe getattr
(it does not exist on IfcPhysicalComplexQuantity, nor in IFC2X3) and is
coalesced to "" when absent.

serialise_cost_quantities built the "Quantities" JSON string by manual
concatenation, inserting quantity.Name and the related element's Name
without any escaping. A name containing a double quote, backslash or
newline produced invalid JSON, breaking any downstream parser (e.g. a
Typst json.decode consumer reporting "failed to parse JSON"). It also
crashed with a TypeError when a name was None (str += None).
Build a Python list and serialise it with json.dumps instead, keeping
the exact same [[name, value], ...] output shape, the element-name
prefix and the unsupported-type behaviour. None names are coalesced to
"" and quantity values are defensively coerced to float.

Documentation claimed that ODS/XLSX output was to a given filename, but
the code actually writes files with generated names in a folder.
(also create the folder if necessary for convenience)
* Export_IfcCostSchedule_to_PDF_improvements
* IfcCostSchedule CSV export: Added ItemIsASum column
New column in the ifc export that tracks if IfcCostItem is a sum, also added a new static method to the IfcDataGetter class.
* IfcCostSchedule CSV export: Added cost quantities column
Cost quantities are a serialsed list containing the name of the quantity and the quantity value.
* IfcCostScheduel PDF export: add options to fine tune export
New options include nested_structure_depth, should_print_cover, should_print_description, should_print_rates, should_print_summary, should_print_cost_ids.
Also pass project currency to typst (still not used).
Added footer with "proudly created with IfcOpenShell".
Updated Cover with formatting and IfcCostSchedule Description
`settings` wasn't defined, so `create_shape` was always resulting in an error. Also, `create_shape` is returning `Triangulation` in this kind of cases, so there's no `.geometry`.
Also removed IfcCircleProfileDef if-check since it's covered by IfcParameterizedProfileDef.
I guess after all it's not very reliable idea since it's possible to have a cost schedule without quantities (even non-SoR) and it's giving users false assumptions that they don't need to worry about "Is Schedule of Rates" flag in some cases.
To prevent confusion with 'Hierarchy' column that's added on the export and make current and export compatible.
Indices now always start from 1 for consistency.
Previously it was saved using Windows 1252 and importing it would fail with an error like so:
```
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x92 in position 650: invalid start byte
```
