* Pairing - initial commit - line functions - sparse Fp12 functions * Small fixes: - Line parametrized by twist for generic algorithm - Add a conjugate operator for quadratic extensions - Have frobenius use it - Create an Affine coordinate type for elliptic curve * Implement (failing) pairing test * Stash pairing debug session, temp switch Fp12 over Fp4 * Proper naive pairing on BLS12-381 * Frobenius map * Implement naive pairing for BN curves * Add pairing tests to CI + reduce time spent on lower-level tests * Test without assembler in Github Actions + less base layers test iterations
