Add fallback for newer msgpack

Browse Source 
Newer msgpack refuses the encoding argument, use raw=False instead.

Further, newer msgpack refuses to accept int as key by default.
Opt into it as the risk is hash collision due to msgpack int being used directly, and
we aren't dealing with untrusted
peer (we only talk to ourselves).
