> [Serialization] Support OrderedDict properly

> Components: Python
> Reporter: Philipp Moritz

> Fix For: 0.8.0
>
>
> At the moment what happens when we serialize an OrderedDict and then
> deserialize it, it will become a normal dict! This can be reproduced with
> {code}
> import pyarrow
> import collections
> d = collections.OrderedDict([("hello", 1), ("world", 2)])
> type(pyarrow.serialize(d).deserialize())
> {code}
> which will return "dict". See also
