* Make it easier to use *just* event payloads by defining the data, and then having event manager macros generate "wrapper structs" * Improve is_*/cast_* APIs to hide details of full event struct. * Create `zmk_event_t` typedef to pass to event handlers. * Bring event names inline w/ consistent `zmk_` prefix.
