ConsenSys/gnark-crypto: v0.6.0

[v0.6.0] - 2021-12-22

Feat

• plookup: added plookup lookup proof
• field: generate optimized addition chains for Sqrt & Legendre exp functions
• field: added field.SetInt64, support for intX and uintX #109
• field: added UnmarshalJSON and MarshalJSON on fields
• field: added field.Text(base) to return field element string in a given base, like big.Int
• field: field.SetString now supports 0b 0o 0x prefixes (base 2, 8 and 16)
• kzg: test tampered proofs whith quotient set to zero
• bls24: Fp-Fp2-Fp4-Fp12-Fp24 tower

Fix

• fixes #104 code generation for saturated modulus like secp256k1 incorrect. added secp256k1 test

Perf

• field inverse is ~30-70% faster (implements Pornin's optimizations)
• bls12-381: faster Miller loop (sparse-sparse mul)
• bls12-381: faster final exp (faster expt)
• bn254: better short addition chain for Expt()
• bn254: addchain with max squares (weighting mul x2.6 cyclosq)
