ResultStore

[dwhswenson]

This object stores the final results, and is specific to the client application. The retry number is passed to this when storing, and it is up to the client application to ensure that the combination of result object and retry number is ensured a unique location in their storage.

• is_failure_result(result: ResultObject) -> bool
• store_result(result: ResultObject, retry: int)
• load_result(label: str, retry: int): this isn't strictly necessary for Exorcist, but may be useful (and will be needed in the client code anyway)

I'm scratching the load_result method here -- it feels application-specific. Client subclasses will likely want to create it, but it feels out of scope for Exorcist.
