Not copying the "PrintTitle" settings to the output for XLSX format

[cklee1967]

Environment

• YARG version: 2.2.8.

Description of the bug or enhancement

When using the XLSX report template, I have set the "Rows to repeat at top" in the Page Setup -> Sheet tab. This allows me to have certain rows to repeat on each page, when I print it in PDF. However, currently this is not copied to the result output XLSX file. I have analyzed the code and I think the XlsxFormatter needs to copy a defined name "_xlnm.Print_Titles", from the template file to the result output file, so that this setting is preserved/copied to the output.

• Minimal reproducible example
  Create an XLSX template and the "Rows to repeat at top" parameter in the Page Setup -> Sheet tab.
  Generate the output XLSX file and check this setting again.

• Expected behavior
  It should have been copied over.

• Actual behavior
  It is missing.
