Set the bounding box coordinates to null when out of range

[maximearmstrong]

What problem is your feature request trying to solve? We extract the coordinates of the bounding box from a given dataset and keep these coordinates without checking their values. Sometimes, we end up extracting invalid coordinates (out of range). The coordinates should be set to null in such a case.

Describe the solution you'd like Make sure that the extracted coordinates are valid. If not, set the coordinates to null.

Suggestion from a consumer perspective: While it's not valid GTFS, it would be good to still get a bounding box for such GTFS feeds based on the valid stops in the feed, as the feed otherwise might go undetected.

How about this: Rather than returning a null bounding box, ignore those stops that have invalid/missing coordinates and calculating the bounding box only based on valid stops.
