External Storage Options

In issue #134 there is some work related to offloading plugins to S3, I was going to use @bradyvercher's example as a starting point as a base for creating a Cloudflare r2 implementation since their library has support for the S3 APIs so the approach should be very similar. Just wondering if that is still a good base example since satispress recently had a 2.0 release so I wasn't sure if the architecture for implementing this was still the best approach.

@aaronware The latest release mostly had some minor PHP compatibility and dependency updates. There weren't any major architecture changes, so that's still a good starting point. Your adapter just needs to implement the storage interface.
