* Typing: events.py * Remove unused variable * Fix return Any from return statement Not all elements from the event dict are sure to be something that can be evaluated See e.g.: https://github.com/python/mypy/issues/5697 * Sort out Event disambiguity There was a name collision of multiprocessing Event type and frigate events Co-authored-by: Sebastian Englbrecht <sebastian.englbrecht@kabelmail.de>
