Consider the following options scenario:
Option.builder("1").longOpt("one").hasArgs().build()
Option.builder("2").longOpt("two").hasArg().required().build()
with the following args:
String[] args = {"--one","arg1","-2","arg2"}
It should consider -2 as an argument or an option? Because, the option 2 is set
to be required.
Currently, -2 is being treated as an argument
