This is done with the intention to add new {Get,Subscribe}ActorEvents in a
future release (i.e. soon!) with both decoded values (dag-json represented)
and simplified (no flags or codec). But because this comes with some
trade-offs wrt fidelity of information (e.g. likely needing to drop events with
badly encoded values, and not retaining original codec), we need to also have
a Raw form of these APIs for consumers that want to take on the burden of
consuming them as they are.
