Recognizes a character that is not in the provided characters.

Complete version: Will return an error if there’s not enough input data.

## Example

    assert_eq!(none_of::<_, _, (&str, ErrorKind)>("abc")("z"), Ok(("", 'z')));
    assert_eq!(none_of::<_, _, (&str, ErrorKind)>("ab")("a"), Err(Err::Error(("a", ErrorKind::NoneOf))));
    assert_eq!(none_of::<_, _, (&str, ErrorKind)>("a")(""), Err(Err::Error(("", ErrorKind::NoneOf))));
