Expand description

Recognizes one or more octal characters: 0-7

Complete version: Will return an error if there’s not enough input data, or the whole input if no terminating token is found (a non octal digit character).

## Example

    fn parser(input: &str) -> IResult<&str, &str> {
        oct_digit1(input)
    }

    assert_eq!(parser("21cZ"), Ok(("cZ", "21")));
    assert_eq!(parser("H2"), Err(Err::Error(Error::new("H2", ErrorKind::OctDigit))));
    assert_eq!(parser(""), Err(Err::Error(Error::new("", ErrorKind::OctDigit))));
