return QCommandLineOptions

I use QCommandLineParser by using the function 

addOption({{"f", "folder" }, "Path to folder" , "path" });

addOption({{"s", "size" }, "Size" , "size" });

and other options with different syntaxes.

It would be beneficial in some situations to get access later in the script to (a copy of) the private variable of the class containing the final list of CLI options, namely

QList<QCommandLineOption> commandLineOptionList;

see https://code.woboq.org/qt5/qtbase/src/corelib/tools/qcommandlineparser.cpp.html#QCommandLineParserPrivate::commandLineOptionList

e.g. with a public function like these:

QList<QCommandLineOption> getOptionList() { return commandLineOptionList};

Thanks.
