 - Fix Conditional Formatting in the Xls Writer to work with rules that contain string literals, cell references and formulae.

 - Resolved formula translations to handle separators (row and column) for array functions as well as for function argument separators; and cleanly handle nesting levels.
 
   Note that this method is used when translating Excel functions between `en_us` and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel).
 
   Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic.
 - Fix for escaping double quotes within a formula [Issue #1971](https://github.com/PHPOffice/PhpSpreadsheet/issues/1971) [PR #2651](https://github.com/PHPOffice/PhpSpreadsheet/pull/2651)
