Request: Supply Chain & Sustainability Info

[GLStephen]

The following items are desired in professor prebid from the Supply Chain & Sustainability task force. I'm opening this ticket to start the conversation, spec and determine what can be added. Some of these may already be in the app. Some may not be possible. There may be some additions after conversation.

Happy to split as needed, but piling into one issue for now:

• [ ] report on protocol for bidder, analytics, cookie sync requests (http2, etc.)
• [ ] compression support in bidder, analytics, syncs
• [ ] cookie sync counts
• [x] media type
• [x] bid response time
• [ ] payload sizes (bidder, analytics, cookie syncs)
• [ ] schain detail
• [x] PAAPI support (work being done already link: https://github.com/WICG/turtledove/issues/937)
• [ ] FPD support (in requests, etc.)
• [x] Use of local storage
• [ ] multiple vs bundled requests
• [ ] type of frame?
