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 #772.
Resolves #691.
