Re: [private-measurement] Interoperable Private Attribution (IPA) (#9)

`campaign_id` is probably a bad name, TBH. `group_id` is better, and because the `source_event` is sent back in the context it was called, it shouldn't need to be bound to the event when called.  I've been thinking that one could assign the `group_id` after the fact (and even change it for two different queries.) The only restriction would be reaching the set grouping threshold (+DP noise).

I haven't thought about assigning multiple `group_id`s to a single event within a single query, and I have the same intuition around increasing complexity in the MPC. Are there scenarios where this would be important to have multiple in a single query (as opposed to sequential, independent queries?)
