Expose openspout api for more export customization

[AshrafBasry]

It would be better to support all openspout functionality like SheetView Options

$writer->getCurrentSheet()->setSheetView(
    (new SheetView())
        ->setShowFormulas(true)
        ->setShowGridLines(false)
        ->setShowRowColHeaders(false)
        ->setShowZeroes(false)
        ->setRightToLeft(false)
        ->setTabSelected(false)
        ->setShowOutlineSymbols(false)
        ->setDefaultGridColor(false)
        ->setView('normal')
        ->setTopLeftCell('A2')
        ->setColorId(1)
        ->setZoomScale(50)
        ->setZoomScaleNormal(70)
        ->setZoomScalePageLayoutView(80)
        ->setWorkbookViewId(90)
        ->setFreezeColumn('B')
        ->setFreezeRow(2)
);

and specially the one I am interested in ->setRightToLeft() 😅
