Description

• handle case where collected events are passed via event_range instead of std::apply it is hard without event_range modification, because currently it stores const std::vector<E>& while we collect in std::array<E, N> here
• for event_range case for transform and filter we can introduce special mode which allows to receive ranges with len less than N. I'm not sure is it needed, but it's nice to have
