Multiple options support

[tanner0101]

I'd like to be able to support multiple values for an option in my CLI tool. For example, something similar to Helm's --values or --set flags:

 helm upgrade --values myvalues.yaml --values override.yaml redis .

Here --values is equal to the array ["myvalues.yaml", "override.yaml"].

I couldn't find a way to do this, so I think it's not supported. I could imagine declaring such an option like this:

[CommandOption("--values")]
public List<string> Values { get; set; }

Thoughts on supporting this? I'd be happy to make a PR if so!

@tanner0101 This should already be possible unless I misunderstand your question:

[CommandOption("--values <VALUES>")]
public string[] Values { get; set; }
