Description

The VersionedIOReadableWritable provides a isCompatibleVersion method that allows users to override to resolve older versions.

This method allows too much space for the user to mess up the implementation, and is much more relevant now because we have an user-facing class TypeSerializerConfigSnapshot which extends VersionedIOReadableWritable.

Instead of a isCompatibleVersion method, it should only expose a narrower int[] getCompatibleVersions that the internal version check uses.
