Updated examples spring 2021

[sknick-iastate]

This PR updates the examples to include all proposed changes for spring 2021.

The examples were expanded to include additional road events modeled after the scenarios here. Below is a summary of the examples that were created:

• Scenario 1 - Simple Workzone
  • First work zone shown with basic lane information
  • Second work zone shown with detailed lane information
  • Third work zone showing a work zone broken into multiple road events
• Scenario 2 - Lane Shift (simple case)
  • Single work zone with lane shift
• Scenario 3 - Shoulder Closure
  • Single work zone but two road events (one in direction of shoulder closure and second in opposite direction)
• Scenario 4 - Road Closure with Detour on Arterial
  • Single work zone with a detour
• Scenario 5 - Work Zone with Bridge Work Overhead
  • This is a simple work zone but added a recurring component. Four additional events were created with a pending status
• Local Access Example
  • Single work zone with local access created. Also included bike lane in example for reference.

Throughout the examples, various optional fields were used as well as a variety of enumerations including the verified location/time. I also tried to remove all depreciated fields. I expect that addition examples can be added in the future based on feedback.

I included reference to the new examples but didn't refer to the scenarios in the discussions. I think it would be valuable to add the link if this is acceptable.

@sknick-iastate wow! Lots of new examples—impressive content.

@sknick-iastate I checked a few of these example files again the schema, using https://www.jsonschemavalidator.net/s/ykYbPPxM, and they did not pass, mostly due to the formatting of road_names. Can you validate each example against the current schema (wzdx_vNext_feed.json in the spring-2021-release branch) and make the necessary changes so that each pass?

Thanks @j-d-b ! I went through and resolved the issues.
