Parse a DER object, expecting a value with specified tag

The object is parsed recursively, with a maximum depth of MAX_RECURSION.

Example

use der_parser::der::{parse_der_with_tag, Tag};

let bytes = &[0x02, 0x03, 0x01, 0x00, 0x01];
let (_, obj) = parse_der_with_tag(bytes, Tag::Integer).expect("parsing failed");

assert_eq!(obj.header.tag(), Tag::Integer);
