#1076 Add MoveSheet and SwapSheets functions to support changing sheet order in the workbook

[Zncl2222]

PR Details

Implement MoveSheet and SwapSheets function to change the order of sheet in the workbook.

• MoveSheet: Moves the sheet to the new position using its current index and the target index. The other sheets will be shifted to the left or the right.

• SwapSheets: Swaps the positions of two sheets in the workbook based on their indices.

Description

Both MoveSheet and SwapSheets functions use the index as their input arguments instead of the SheetName. This is because SheetName is allowed to be duplicated within a workbook. To avoid potential confusion or conflicts caused by duplicate sheet names, the implementation relies on the sheet index.

Here is an example code snippet to reorder the sheet

package main

import (
	"fmt"
	"strconv"

	"github.com/xuri/excelize/v2"
)

func main() {
	f := excelize.NewFile()
	defer func() {
		if err := f.Close(); err != nil {
			fmt.Println(err)
		}
	}()
	for i := 2; i < 10; i++ {
		f.NewSheet("Sheet" + strconv.Itoa(i))
       }
	if err := f.SaveAs("BeforeOrder.xlsx"); err != nil {
		fmt.Println(err)
	}
	if err := f.MoveSheet(7, 0); err != nil {
		fmt.Println(err)
	}
	if err := f.SaveAs("AfterOrder.xlsx"); err != nil {
		fmt.Println(err)
	}
}

Motivation and Context

Allow users to use this package more flexibly. Additional this can resolve the problem that SetSheetName can't update the sheet name in the formula or reference associated with the cell.

Thanks for your pull request. The swap sheet can be implemented by move sheet, due to the principle of minimum availability, I suggest just introducing the MoveSheet function to keep the library core and easy. I made some changes based on your branch.
