closes #622 Pros: * simpler interface, just functions: `create_runtime_from_artifact_bytes()` and `execute_artifact()` Cons: * extra overhead of constructing executor semantics each time I could make it a combination of * `create_runtime_config(params)` (such that we could clone the constructed semantics) * `create_runtime(blob, config)` * `execute_artifact(blob, config, params)` Not sure if it's worth it though. --------- Co-authored-by: Bastian Köcher <git@kchr.de>
