There's no get default sheetname for file

[yasarluo]

there's many funtions with param 'sheet name', but if we want to get active sheet name, we'll use two steps.

activeSheetIdx := f.GetActiveSheetIndex()
activeSheetName := f.GetSheetName(activeSheetIdx)

So, we hope there's only one step that can easily to do this, just like:

activeSheetName := f.GetActiveSheetName()
