For simplicity we now use a unique alpha (subrelation batching challenge) per instance but will not raise it up to NUM_SUBRELATION - 1 power . This is sowe don't blow up the degree of combiner and compilation time. The plan is to generate one alpha per subrelation so batching those only takes the degree of the combiner from dk to (d + k)*d

feat: Protogalaxy Decider and complete folding tests (#3657)
cfdaf9c 
This PR introduces the Protogalaxy decider, now having a complete proof
of concept of the folding protocol for Ultra instances. To enable this,
sumcheck has been modified to work with the same power polynomial as in
protogalaxy paper and can be initialised with a custom `target_sum`.
Moreover, we now use different batching challenges for each subrelation
in sumcheck, essential to ensure a reasonable degree of the combiner
polynomial.

Additional: Minor bug fixed in the computation of \vec{\beta*}. 

Resolves AztecProtocol/barretenberg#772.
Resolves AztecProtocol/barretenberg#691.
