The `book_append_sheet` utility function appends a worksheet to the workbook.
The third argument specifies the desired worksheet name. Multiple worksheets can
be added to a workbook by calling the function multiple times.
be added to a workbook by calling the function multiple times. If the worksheet
name is already used in the workbook, it will throw an error.
_Append a Worksheet to a Workbook and find a unique name_
```js
var new_name = XLSX.utils.book_append_sheet(workbook, worksheet, name, true);
```
If the fourth argument is `true`, the function will start with the specified
worksheet name. If the sheet name exists in the workbook, a new worksheet name
will be chosen by finding the name stem and incrementing the counter:
```js
XLSX.utils.book_append_sheet(workbook, sheetA, "Sheet2", true); // Sheet2
XLSX.utils.book_append_sheet(workbook, sheetB, "Sheet2", true); // Sheet3
XLSX.utils.book_append_sheet(workbook, sheetC, "Sheet2", true); // Sheet4
XLSX.utils.book_append_sheet(workbook, sheetD, "Sheet2", true); // Sheet5
```
