Function mozrunner::firefox_args::get_arg_value

pub fn get_arg_value<'a>(
    parsed_args: impl Iterator<Item = &'a (Option<Arg>, Option<String>)>,
    arg: Arg
) -> Option<String>

Given an iterator over all arguments, get the value of an argument

This assumes that the argument takes a single value and that is either provided as a single argument entry (e.g. ["--name=value"]) or as the following argument (e.g. `[“–name”, “value”])
