Add unparse extension with args (string[]) as return value

[kapsiR]

It would be cool if I can use the unparsed string with the parser again.

e.g.

public static string[] FormatCommandLineArgs<T>(this Parser parser, T options, Action<UnParserSettings> configuration)

If the options instance is manually created, it would be possible to let commandline handle some default stuff:

        public async Task RunAsync(string[] args)
        {
            var parserResult = _parser.ParseArguments<MyOptions1, MyOptions2, MyOptions3>(args);

            await parserResult.MapResult(
                  async (MyOptions1 opts) => await Run1Async(opts),
                  async (MyOptions2 opts) => await Run2Async(opts),
                  async (MyOptions3 opts) => await Run3Async(opts),
                  async (IEnumerable<Error> errors) => await HandleParseErrorAsync(errors));
        }

        public async Task RunWithOptionsAsync<T>(T options)
        {
            string[] unparsedArgs = _parser.FormatCommandLineArgs(options);

            await RunAsync(unparsedArgs);
        }

You can split the string generated from FormatCommandLineArgs to string[].
It is planned to provide this Extension method.

@moh-hassan Thanks for adding this to the 2.9 milestone.
Splitting the string manually is painful, as you have to honor all different kinds of possibilities (especially with paths)

As alternative, this also would be a lot easier if I could provide the separator for FormatCommandLineArgs.

@kapsiR
Yes, you are correct.
It's planned to provide a specialized splitter for FormatCommandLineArgs.
