Rename WZDxFeed to WorkZoneFeed (or similar)

[j-d-b]

This issue proposes renaming the WZDxFeed object to WorkZoneFeed.

Background

WZDx v4.0 defines the following feeds:

• WZDxFeed: describes high-level information about work zone events ocurring on roadways (called "road events") that impact the characteristics of the roadway and involve a change from the default state (such as a lane closure). This is the original work zone data exchange feed and the only feed that WZDx defined until version 4.0.
• RoadRestrictionFeed: describes the location and details of restrictions on roadways.
• SwzDeviceFeed: describes information (location, status, live data) about field devices deployed on the roadway in work zones. (note this may be renamed to DeviceFeed as proposed in #242)

Issue

There are several issues with the naming of WZDxFeed, mostly related to the name being confusing and only there for historical reasons:

• All feeds are WZDx feeds, so it is confusing to have one of the feeds named WZDxFeed
• Each of the feeds are WZDx feeds, so when referring to a feed out of context, it would be preceded by "WZDx". Thus, the WZDxFeed is the WZDx WZDxFeed
• The RoadRestrictionFeed and SwzDeviceFeed (to be DeviceFeed) provide indication of what the feed includes while the WZDxFeed is more general

Proposed Change

• Rename the WZDxFeed to WorkZoneFeed

Then (assuming #242 is implemented) WZDx would define the following feeds:

• WorkZoneFeed: describes high-level information about work zone events occurring on roadways (called "road events") that impact the characteristics of the roadway and involve a change from the default state (such as a lane closure). This is the original work zone data exchange feed and the only feed that WZDx defined until version 4.0. It was previously called the "WZDxFeed".
• RoadRestrictionFeed: describes the location and details of restrictions on roadways.
• DeviceFeed: describes information (location, status, live data) about field devices deployed on the roadway, typically in work zones.

Note that this is a rename of the feed object and feed as referenced throughout WZDx documentation and has no impact on the specification content or structure.

I highly support this change - it improves legibility and future proofing. Thanks!

Based on the WZDx Specification Update Subgroup Meeting on May 5, 2022, the rename to WorkZoneFeed will be implemented for WZDx v4.1.
