* Change CycleFold approach: Instead of having a single CycleFold circuit that checks the 2 forign scalarmul of the main circuit instances, now there are 2 separated CycleFold circuits each of them checking a single foreign scalarmul. Increasing the number of constraints of the AugmentedFCircuit, but reducing the number of constraints in the CycleFold circuit, which will translate into reducing the number of constraints in the Decider circuit. * CycleFold circuits checks in AugmentedFCircuit: - update NonNativeAffineVar to work with NonNativeFieldVar directly instead of FpVar comming from NonNativeFieldVar.to_constraint_field() - include in AugmentedFCircuit intermediate steps inbetween CycleFold circuits, and update the internal checks of the CycleFold circuits Pending to document the new CycleFold circuits approach and better variable namings, rm unwraps, etc * matrix_vec_mul_sparse gadget: skip value * v[col_i] mul when value==1 Saves a notable amount of constraints since there is a notable amount of 1 values in R1CS matrices. * Reuse computed vector of U_i Reuse computed vector of U_i, saving 4k constraints in AugmentedFCircuit. * fixes post last rebase to main * rm test_augmentedfcircuit since it is already tested in test_ivc (and is a slow computation) * rm dbg!() * small fixes after last main rebase
