* 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.

* Add Decider impl for Nova onchain
Add Decider impl for Nova onchain.
Update also the Decider trait.
Nova onchain decider: (compressed SNARK / final proof), in order to
later verify the Nova+CycleFold proofs onchain (in Ethereum’s EVM).
* PR review updates and few other changes
* Add KZG commitment scheme adapted to vector commitment
Add KZG commitment scheme adapted to vector commitment
Also move the `src/pedersen.rs` into `src/commitment/pedersen.rs` where
it will coexist with `kzg.rs` and the trait defined in
`src/commitment/mod.rs`.
* Adapt Pedersen into the new CommitmentProver trait
* add CommitmentProver (Pedersen&KZG) homomorphic property test
* polishing
* Use divide_with_q_and_r, rename skip_first_zero_coeffs

* Implement Nova IVC's new & prove_step methods
Implement Nova IVC's new & prove_step methods (without CycleFold part yet)
* transcript.absorb_point err handling, and update C.xy() usage
* add transcript usage to IVC prove, add NovaTranscript trait extending Transcript trait, refactor NIFS.P to allow absorbing in transcript inbetween
* Implement Nova's IVC.V method (without CycleFold part yet)
* clippy lints
* move challenge r computation in-circuit
* reuse computed points with coordinates over CF (non-native) to save constraints in AugmentedFCircuit
(constraint count went down ~6k)
* rm 128 bit constant
* add params to Errors
* Updates from review suggestions. Additionally refactored nova/nifs fold, and rm transcript from nova/IVC.
- Updates from PR suggestions
- Additionally updated:
- in nova/nifs.rs: reuse folded_committed_instance for verify_folded_instance, computationally is the same, but reusing the same code so avoiding duplication and having an error on one of the two versions.
- in nova/ivc.rs: remove transcript from IVC (not needed, it uses the RO)
* impl AugmentedFCircuit non-base case
* add multiple iterations to AugmentedFCircuit test
* implement base case on AugmentedFCircuit and test
* Update cmE of E=0-vec to work as zero point
Update cmE of E=0-vec to work as zero point instead of as cm(0-vec)
* patch r1cs-std dep to a cherry-picked version with the zero-scalar-mult fix
* refactor FCircuit to make it more suitable inside the AugmentedFCircuit
* Port HyperNova's multifolding from https://github.com/privacy-scaling-explorations/multifolding-poc adapting and refactoring some of its methods and structs.
Note: adapted mle.rs methods from dense to sparse repr.

* HyperNova: move CCS struct outside of LCCCS & CCCS
HyperNova nimfs: move CCS structure outside of LCCCS & CCCS, to avoid
carrying around the whole CCS and duplicating data when is not needed.
Also add feature flags for the folding schemes.

* Implement Nova's NIFS.Verify circuits (with CycleFold)
- Add circuit for NIFS.Verify on the main curve to check the folded `u`
& `x`
- Add circuit for NIFS.Verify on the CycleFold's auxiliary curve to
check the folded `cm(E)` & `cm(W)`
- Add transcript.get_challenge_nbits
- Add tests for utils::vec.rs
* replace bls12-377 & bw6-761 by pallas & vesta curves (only affects tests)
We will use pallas & vesta curves (for tests only, the non-tests code
uses generics) for the logic that does not require pairings, and while
Grumpkin is not available
(https://github.com/privacy-scaling-explorations/folding-schemes/issues/12).
* update links to papers to markdown style
