#get_open_intervals(opening_hours_string, from, to) ⇒ Object

Open intervals of an opening hours string inside a concrete window, as [{ start: Time, end: Time }], sorted and clamped to [from, to].

Unlike get_time_iterator, this applies "off" rules and intervals crossing midnight, and covers every year the window touches rather than the current one.
