It parse input argument vector to vector of string truple

Example:
    
    use arg_pars;

    fn main() {
        let arg_vec = arg_pars::parse(std::env::args().collect());
        for arg in arg_vec {
            println!("{}:{}", arg.0, arg.1);
        }
    }

    input: ...> .\main.exe --b --c --s=45 -f=this is long name of file
    output: main.exe:true
            b:true
            c:true
            s:45
            f:this_is_long_name_of_file
