   Note: This type exists only to uniquely identify places bids came from, avoiding confusion in
   cases like bids made by the same interest group in different component auctions, or additional
   bids reusing names of regular interest groups. Implementations can likely find a more efficient
   way of achieving the same effect. Note that bids returned when `generateBid()` returns multiple
   items all share a key, as they share reporting information, too.
