Expand description

Create oracles for the bivariate product of an inner oracle with shift indicator.

Projects to first block_size() vars. Returns metadata object with oracle identifiers. Pass this object to:

projected_bivariate_claim to obtain sumcheck claim
shifted_sumcheck_witness to obtain sumcheck witness
