ItemIsASum and Quantities are exporter columns that were missing from
MAIN_CSV_HEADER_COLUMNS, causing them to be misidentified as numeric cost
value categories on re-import. Also initialise rate_cost_schedule to None
before the search loop to avoid UnboundLocalError when no match is found.
Generated with the assistance of an AI coding tool.
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
```
