 * Implementation of Excel function TEXTJOIN()
 * <b>Syntax</b><br>
 * <b>TEXTJOIN</b>(<b>delimiter</b>, <b>ignore_empty</b>, <b>text1</b>, <b>[text2]<b>, ...)<p>
 * <b>delimiter</b> A text string, either empty, or one or more characters enclosed by double quotes, or a reference to a valid text string.
 * If a number is supplied, it will be treated as text.<br>
 * <b>ignore_empty</b> If TRUE, ignores empty cells.<br>
 * <b>text1</b> Text item to be joined. A text string, or array of strings, such as a range of cells.<br>
 * <b>text2 ...</b> Optional. Additional text items to be joined. There can be a maximum of 252 text arguments for the text items, including text1.
 * Each can be a text string, or array of strings, such as a range of cells.<br>
 * @since POI 5.1.0
