Replace a content type in this package.

A typical scneario to call this method is to rename a template file to the main format, e.g. ".dotx" to ".docx" ".dotm" to ".docm" ".xltx" to ".xlsx" ".xltm" to ".xlsm" ".potx" to ".pptx" ".potm" to ".pptm"

For example, a code converting a .xlsm macro workbook to .xlsx would look as follows:

     OPCPackage pkg = OPCPackage.open(new FileInputStream("macro-workbook.xlsm"));
     pkg.replaceContentType(
         "application/vnd.ms-excel.sheet.macroEnabled.main+xml",
         "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml");

     FileOutputStream out = new FileOutputStream("workbook.xlsx");
     pkg.save(out);
     out.close();

oldContentType - the content type to be replaced
