Expand description

Recognizes a little endian signed 4 bytes integer.

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

    use nom::number::streaming::le_i32;

    let parser = |s| {
      le_i32::<_, (_, ErrorKind)>(s)
    };

    assert_eq!(parser(&b"\x00\x01\x02\x03abcd"[..]), Ok((&b"abcd"[..], 0x03020100)));
    assert_eq!(parser(&b"\x01"[..]), Err(Err::Incomplete(Needed::new(3))));
