Make sure cold call graph is everything we plan on sending minus initial CIDs being pushed. Note this impacts the ability to create a bloom in parallel... need to know what is being sent before creating it so we don't set. And bloom doesn't allow unsetting, unless we use a different filter type that supports subtraction.

Confirm our want list / subgraph roots is just roots, not all CIDs. Noting this because it seemed pretty long in some tests, but likely just the nature of the randomly gen'd data.

Make sure we're adding each received block to our copy of the bloom.
