Parsing command line arguments as a std::string

[huangzonghao]

Wondering if there is any plan to add cxxopt::Options::parser(int argc, std::string argv) into the library, or accept a pull request for this function.

I think a good reason to include this feature in the library is to deal with protocol calls from browser or other applications where all the input arguments are passed in as a long string in url format. And currently I am running a pre-parser to convert the string to char** argv, but I think it would be good to have the library parse the string directly.

I can't see any reason not to do that. I can't really work on it right now, but I will look at a PR.
