Expand description

Recognizes a big endian signed 2 bytes integer.

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

    use nom::number::streaming::be_i16;

    let parser = be_i16::<_, (_, ErrorKind)>;

    assert_eq!(parser(&b"\x00\x01abcd"[..]), Ok((&b"abcd"[..], 0x0001)));
    assert_eq!(parser(&b""[..]), Err(Err::Incomplete(Needed::new(2))));
