I think there is a misalignment between the release version 2.0.1 on [npm](https://www.npmjs.com/package/react-native-cache) and the one on [github](https://github.com/timfpark/react-native-cache). On npm is missing the new feature of "ttl" policy. As I can see the latest [commit](https://github.com/timfpark/react-native-cache/commit/2b3b90e37235d67958cb2a32ede1520f1ab20e70) is missing. Cheers.
