Subject: [PATCH] TripleLift: CCPA support (#4628)

* Add IdentityLink support and fix UnifiedId.

It appears we've been looking for UnifiedId userIds
on the bidderRequest object, when they are found on bidRequests.
This commit fixes that error, and adds support for IdentityLink.

* change maintainer email to group

* TripleLift: Sending schain (#1)

* Sending schain

* null -> undefined

* Hardcode sync endpoint protocol

* Switch to EB2 sync endpoint

* Add support for image based user syncing

* Rename endpoint variable

* Add assertion

* Add CCPA query param

* Simplify check for usPrivacy argument
