Custom xml

[myk93]

This pull request introduces support for adding custom XML parts to generated Excel workbooks, specifically for registering Connected Workbooks metadata. The changes include new utilities for managing custom XML items, updating content types and relationships, and integrating these steps into the workbook generation process. Additionally, several constants and error messages were added to support these features.

Custom XML support for Connected Workbooks:

• Added new utility functions in xmlInnerPartsUtils.ts to:

  • Determine the next available custom XML item number,
  • Check for the existence of a Connected Workbook custom XML item,
  • Add content type overrides for custom XML items,
  • Add relationships for custom XML items in the workbook relationships file.

• Introduced a new function addCustomXMLToWorkbook in xmlPartsUtils.ts that orchestrates the creation and registration of custom XML items when generating a workbook.

• Integrated the custom XML addition step into the main workbook generation pipeline in workbookManager.ts.

Constants and error handling enhancements:

• Added new constants to constants.ts for custom XML paths, folder names, XML element/attribute names, error messages, and custom XML content templates.
• Updated imports and usages to leverage new constants for improved maintainability and clarity.

Other minor improvements:

• Updated the package version in package.json to 3.4.0-beta.
• Improved error handling and folder path management for table file lookups.

These changes ensure that every generated workbook includes the necessary custom XML data and registrations for Connected Workbooks, improving interoperability and metadata support.
