Rule to capture consecutive stops on a trip have the same arrival and departure times
Describe the problem
The current validator seems unable to catch the following unreasonable data：
In stop_times.txt, multiple stops in a single trip have the same departure_time and arrival_time.
Such data implies that the vehicle must pass through these stops (including the time for passengers to get on and off) within 1 minute. While this might be possible for 2 consecutive stops that are close to each other, we can reasonably doubt the accuracy of the data in cases where there are more than 3 stops.
The existing fast_travel_between_consecutive_stops rule cannot cover this issue. For example, if 10 consecutive stops in a trip have the same time, the fast_travel_between_consecutive_stops rule will not be triggered as long as the distance between each pair of consecutive stops is sufficiently close.
Describe the new validation rule
If more than 3 consecutive stops (including 3) in a trip have the same departure_time and arrival_time:
trigger a warning
