8c46517522 zkpbinding: use proper field size for BLS12-381
It's not differ from BN254, but we'd better use the proper package.

ff260a6a9b zkpbinding: allow to handle serialisation format of gnark >= v0.9.0
An upgrade from gnark v0.8.X to v0.9.0 changes serialization format of verifying/proving keys
and proofs. In neo-go zkpbinding package we have to support both at least for now, because
gnark@v0.9.0 requires minimum go 1.19.

9e74fc5b47 zkp: add end-to-end Groth-16 proof generation/verification example
The example shows that the proover knows the solution of the cubic
equation: y = x^3 + x + 5. The example is constructed for BLS12-381
curve points using Groth-16 prooving algorithm. The example includes
everything that developer needs to start using ZKP on the NEO platform
with Go SDK:
1. The described cubic circuit implementation.
2. The off-chain proof generation with the help of gnark-crypto library.
3. Go verification contract generation and deployment with the help of
   NeoGo libraries.
4. The on-chain proof verification for various sets of input data.
