Add XSSFOptimiser - XSSF equivalent of HSSFOptimiser (#952) ...

* Add XSSFOptimiser - XSSF equivalent of HSSFOptimiser

Adds optimization methods for XSSF workbooks to address style explosion
issues. HSSFOptimiser exists for HSSF but no equivalent existed for XSSF.

Methods added:
- optimiseCellStyles(XSSFWorkbook): Remaps cells using duplicate styles
  to canonical (first) occurrence
- optimiseFonts(XSSFWorkbook): Updates style font references to canonical
  fonts

Implementation uses a safe remapping approach rather than removing entries
from XML, which avoids XmlValueDisconnectedException issues caused by
StylesTable's internal list becoming disconnected from CTStylesheet.

Includes comprehensive test coverage in TestXSSFOptimiser.

Closes #951

* Address PR review comments

- Add "since 6.0.0" javadoc tag to XSSFOptimiser class
- Use Locale.ROOT in String.format() to comply with forbidden-apis check
