feature/reduce-event-gather-complexity

Had parts of this code sitting around. Finished it up in ~30 minutes. Need to test on a dev instance but pretty confident it will work.

Main change is resolving #230 -- moving from processing all sessions in a single flow to producing multiple flows, one for each session. I haven't touched any multiprocessing just yet to be safe.

Heading out for the night, might get a chance to test this tomorrow. If it works on a dev instance will fast merge and deploy
