Duplicate conditional style to a range of cells.

Please note that this will overwrite existing cell styles for cells in range!

@param Conditional[] $pCellStyle Cell style to duplicate
@param string $pRange Range of cells (i.e. "A1:B10"), or just one cell (i.e. "A1")

@throws Exception

@return Worksheet
