The `run()` method takes a timeline and returns a promise that is resolved when the experiment finishes. Hence, jsPsych can now be initialized without starting an experiment. This re-enables usage of `jsPsych.timelineVariable()` in timeline definitions and repairs exclusion checks and extension loading.
