feat(replays): Separate I/O and compute portions of the runtime into different Arroyo tasks

[cmanallen]

I/O and compute was previously separated into different stages of the same task. With this PR we add a two-step recording consumer which separates compute and I/O between two different Arroyo tasks. This allows us to continue processing messages while we upload files to GCS.

This does not overwrite our current production consumer. We deprecate the old recording_buffered consumer and replace it with this new "two-step" consumer. We'll test it in S4S before transitioning our production consumer.
