Feature request: Store network event for when there is a network connection

Essentially: have a buffer: when a network request is made (especially `POST`/`PUT`), send it to the buffer and if there is a network connection process the request right away.

If there's no network, just keep it in the buffer until the network is available again.

No files, tests, or entry points are named. Start by locating how JASONETTE-iOS sends POST and PUT requests and how it detects network availability; then clarify buffer persistence, retry behavior, and the tests needed to show requests are deferred offline and processed when connectivity returns.
