Expand description

Recognizes a big endian signed 3 bytes integer.

Streaming version: Will return `Err(nom::Err::Incomplete(_))` if there is not enough data.

    use nom::number::streaming::be_i24;

    let parser = be_i24::<_, (_, ErrorKind)>;

    assert_eq!(parser(&b"\x00\x01\x02abcd"[..]), Ok((&b"abcd"[..], 0x000102)));
    assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(3))));
