Work with spreadsheet files

## Method Signature

```
Spreadsheet(path=[any], sheetname=[any], xmlformat=[any])
```

### Arguments

| Argument    | Type      | Required | Description                                                                                       | Default |
| ----------- | --------- | -------- | ------------------------------------------------------------------------------------------------- | ------- |
| `path`      | `STRING`  | `false`  | The path to the spreadsheet file to load or the path where the spreadsheet file will be stored at |         |
| `sheetname` | `STRING`  | `false`  | The name of the sheet to work with (optional). Default is "Sheet1".                               |         |
| `xmlformat` | `BOOLEAN` | `false`  | Whether the spreadsheet should use XML format (.xlsx). Default is true.                           | true    |

## Examples

Work with the fluent API SpreadsheetFile class:

```js
// Using fluent API for method chaining
var sheet = new SpreadsheetFile()
    .createSheet( "Sales" )
    .addRow( [ "Date", "Amount" ] )
    .addRow( [ "2024-01-01", 1500 ] )
    .addRow( [ "2024-01-02", 2000 ] )
    .formatRow( 1, { bold = true, background = "CCCCCC" } );
```

Convert between BIF and fluent APIs:

```js
// BIF approach
var bifSheet = SpreadsheetNew();

// Fluent approach
var fluentSheet = new SpreadsheetFile();

// Both work with same operations
```
