Consider triple pairs for storage instead of singular ones

[ChaoticTempest]

Currently we pop entirely separate triples and check their intersection. This can lead to a series of popping and pushing back into redis storage if the intersection of participants does not meet the requirements. How about before storing them, we create pairings of them such that this intersection at least meets the threshold requirements.

But note this basically frontloads this subset logic. To circumvent this even further, we should generate at least pairs of triples at the same time with the same participant set. Also, cait-sith allows us to do batch triple generation with the same participant set allowing us to group these triples without our complex logic of intersections.
