DEPR: msgpack

[jreback]

msgpack uses the internal format on the wire. this makes for only pandas producers and consumers, but with pyarrow support now fully handling this case (and better performing), it is time to deprecate msgpack.

Deprecated since version 2.0: The custom serialization functionality is deprecated in pyarrow 2.0, and will be removed in a future version. Use the standard library pickle or the IPC functionality of pyarrow (see Streaming, Serialization, and IPC for more).
