chore: using spi for TimedAction and ESE (#45)

* snapshot runtime version

* chore: SDK implementation of SpiEventSourcedEntity

* first stab, untested
* corresponds to EventSourcedEntitiesImpl, ReflectiveEventSourcedEntityRouter, EventSourcedEntityRouter

* descriptor

* setState

* error code

* isDeleted

* chore: updating SDK for work with embedded TimedAction

* Apply suggestions from code review

* ignoring deprecation

* runtime versions
