As far as I read it, Kryo 3.x is not strictly serialization compatible with
2.x, hence the major version number bump.
If the interfaces are still stable, then it should be fine to bump the
chill dependency version, exclude any kryo dependency, and add our own 2.x kryo
dependency. I would prefer that approach.
