Subject: [PATCH] TripleLift: Sending schain (#4375)

* 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
