 * Persistor implementation using AsyncStorage
 * From https://github.com/segmentio/analytics-react-native/blob/master/packages/sovran/src/persistor/async-storage-persistor.ts
 *
 * This is almost exactly the same as the default persistor that segment uses however our build was not liking the persistor linked above due to its
 * use of require('@react-native-async-storage/async-storage'). The require was resolving to { default: AsynctStorage } instead of just AsyncStorage
 * so calls to AsyncStorage.getItem and AsyncStorage.setItem were not happening because they were undefined. This is a workaround to that issue.
