This PR contains the work done to update the live test data to its latest version. Plus other improvements have been made:
* conformed the `AmiiboServiceError` error to the `LocalizableError` protocol,
* improved the `ISODateTimeTranscoder` transcoder to handle the decoding of both ISO dates and timestamps,
* removed a force-unwrapped from the `AmiiboLiveClient` type.
