Booking systems allow the booking of merged meeting rooms, which can result in one meeting room being bookable as two or more rooms. When mapping spaces from Serraview against resources (spaces) in booking systems, we need to identify overlapping spaces and group them together under a unique space ID.

For example, two meeting rooms, each with 5 seats, can be booked separately as Room A and Room B. However, when merged, they can be booked as Room C with 10 seats.

The reason for having merged rooms instead of booking Room A and Room B together is that when a user searches for a room with 10 seats, smaller rooms won't be shown in the results.
