Provide a default cache implementation (probably using the non-android version of [DataStore](https://developer.android.com/topic/libraries/architecture/datastore#kts)). We currently have [`BasicCacheProvider`](https://github.com/instacart/truetime-android/blob/master/library/src/main/java/com/instacart/truetime/BasicCacheProvider.kt#L6-L6) but will get wiped out on Application restart. `DataStore` would be a better alternative for Android users.
