We have added public <code>WindowedSerdes</code> to allow users to read from / write to a topic storing windowed table changelogs directly.
In addition, in <code>StreamsConfig</code> we have also added <code>default.windowed.key.serde.inner</code> and <code>default.windowed.value.serde.inner</code>
to let users specify inner serdes if the default serde classes are windowed serdes.

We have added support for methods in <code>ReadOnlyWindowStore</code> which allows for querying <code>WindowStore</code>s without the necessity of providing keys.
