/**
* A simple, asynchronous, persistent, key-value storage system designed as a
* backend to the AsyncStorage JS module, which is modeled after LocalStorage.
*
* Current implementation stores small values in serialized dictionary and
* larger values in separate files. Since we use a serial file queue
* `RKFileQueue`, reading/writing from multiple threads should be perceived as
* being atomic, unless someone bypasses the `RCTAsyncLocalStorage` API.
*
* Keys and values must always be strings or an error is returned.
