It returns (ctxt, num_messages, num_ticks, tick) where ctxt is the updated layer 2 context (with the new PVM state), num_messages is the number of messages, num_ticks is the number of ticks taken by the PVM for the evaluation and tick is the tick reached by the PVM after the evaluation.

state_of_tick plugin node_ctxt ?start_state ~tick level returns Some (state, hash) for a given tick if this tick happened before level. Otherwise, returns None. If provided, the evaluation is resumed from start_state.
