Bug fix: Follow up to #46

SQL result and table export to MS-Excel files: The options to make header rows bold and centered did not
  work for MS-Excel but for Libre Office only.
  Details of the fix:
  - Apache-Poi was upgraded to version 5.3.0.
  - SQuirreL deliberately dropped dependency on Log4J in 2022. As Apache-Poi 5.3.0 directly depends
    on Log4J, SQuirreL now has a Log4J mock to make Apache-Poi 5.3.0 work.
