* add class UnpersistedEventContext * modify create new client event to create unpersistedeventcontexts * persist event contexts after creation * fix tests to persist unpersisted event contexts * cleanup * misc lints + cleanup * changelog + fix comments * lints * fix batch insertion? * reduce redundant calculation * add unpersisted event classes * rework compute_event_context, split into function that returns unpersisted event context and then persists it * use calculate_context_info to create unpersisted event contexts * update typing * $%#^&* * black * fix comments and consolidate classes, use attr.s for class * requested changes * lint * requested changes * requested changes * refactor to be stupidly explicit * clearer renaming and flow * make partial state non-optional * update docstrings --------- Co-authored-by: Erik Johnston <erik@matrix.org>
