Generated extra line breaks

[H0LIXI]

Hello, I found that after fix this issue [https://github.com//issues/1655], another issue appeared.

When the newline character in the previous file was x000D\r\n, opening it in Excel would show only one line break.
After saving with version Epp.7.5.0, x000D\r\n becomes \r\r\n, and opening it in Excel results in two line breaks. After saving in Excel, it becomes \r\n\r\n.

If it's a newly created file, there might not be an issue, but if it's a file that was handled by an older version, upgrading the plugin might cause an increase in newline characters.

I'm not sure if directly removing \r when saving the text, or adjusting \r...\r\n to \r\n, is a feasible solution.

You can use this file to test. Observe the changes in cell A3.
Test-rrn.xlsx

// Read any cell and then save.
using (var excel = new ExcelPackage(newPath))
{
    var sheet = excel.Workbook.Worksheets.FirstOrDefault();
    var excelName = sheet.Name;

    for (var i = 1; i <= 2; i++)
    {
        for (var j = 1; j <= sheet.Dimension.Columns; j++)
        {
            var cellVal = sheet.Cells[i, j].Text;
        }
    }

    excel.Save();
}

Thanks for reporting. I'll have a look at it.

I'm not sure why Excel makes a difference on x000D\r\n and \r\r\n. This seems weird.

I tried using Microsoft's Microsoft.Office.Interop.Excel library to read the cell, and x000D\r\n was read as \r\n. It seems that x000D was ignored.
