Serialize support for messagepack

Limitation

MessagePack requires the length header of arrays and maps to be written before any elements are encoded. Therefore this serializer needs serde to provide the exact length up front. If serde calls serialize_seq(None) or serialize_map(None), this serializer returns Error::SeqLenNone.

Examples with serde(flatten):

use serde::Serialize;
use std::collections::HashMap;

// Fails
#[derive(Serialize)]
struct Inner { b: u8, c: u8 }

#[derive(Serialize)]
struct Outer {
    a: u8,
    #[serde(flatten)]
    extra: Inner,
}

let mut buf = [0u8; 32];
let v = Outer { a: 1, extra: Inner { b: 2, c: 3 } };
let err = messagepack_serde::ser::to_slice(&v, &mut buf).unwrap_err();
assert_eq!(err, messagepack_serde::ser::Error::SeqLenNone);
