PHP 8.1 Support Issue - Passing null pararmeter deprecated

Please see error below:

Severity: 8192

Message: htmlspecialchars(): Passing null to parameter #1 ($string) of type string is deprecated

Filename: php_xlsxwriter/xlsxwriter.class.php

Line Number: 760

Adding ternary to line 760 is a suggested fix:

return strtr(htmlspecialchars($val ?: '', ENT_QUOTES | ENT_XML1), $badchars, $goodchars);//strtr appears to be faster than str_replace
