Allow indicating a sidewalk closure without providing lane-level information #373

Discussed in https://github.com/usdot-jpo-ode/wzdx/discussions/372

Originally posted by **Charlie-Henry** July 11, 2024 Looks like the only place to supply sidewalk closures in in the `lanes` [details](https://github.com/usdot-jpo-ode/wzdx/blob/main/spec-content/objects/Lane.md). We are wondering if it is possible to report a sidewalk closure without knowing the order of lanes (which breaks business rule 2). Making the cross section of every road (including sidewalks/bike lanes/parking) a requirement is a pretty impractical for a City DOT. [vehicle_impact](https://github.com/usdot-jpo-ode/wzdx/blob/main/spec-content/enumerated-types/VehicleImpact.md) is also pretty car-centric and doesn't help this use case.

Proposed solution

Enhance the Vehicle Impact Enumerated Type to support indicating that a sidewalk is closed so that feed producers who want to provide sidewalk impact do not have to have lane-level information.

Thanks Jacob!

Our specific use case comes from our permitting system where we are able to track work zones at the street-segment level. It tracks closures to the general purpose lanes, parking lanes, and sidewalks. Any combination of those can be closed.

So, it's possible we could have one general purpose lane closed + a sidewalk. We do not have the actual lane cross-section to provide that level of detail needed in business rule 2. I'm not sure if adding a "closed sidewalk" to vehicle_impact would solve this, because we may want to show some_lanes_closed at the same time? Unfortunately the sidewalk and roadway share the same street segment & geometry.
