Add BW6-767 curve and update BW6-761 to use the new bw6 model (#156) * Rework bw6-761 to bw6-767 use bls12-381 instead of 377 for test imports fix the inline comments with correct name and params Set the right base field Equation for base curve is y2 = x3 + 1 fill in pairing params adapt sage scripts with correct moduli calculate the correct cubic non residue correct the parameter B in the curve equation remove the specialized method for mult by nonresidue nonresidue is two, so default will be doubling calculate more correct parameters for fq3 `TRACE_MINUS_ONE_DIV_TWO` and `QUADRATIC_NONRESIDUE_TO_T` compute the right fq3 & fp6 frobenious coefficients calculate the cofactor for g1 use the g1 generator from gnark's fork use the right g2 equation g2 cofactor is slightly smaller than g1 cofactor get the g2 generators from gnark's fork update g1 and g2 curve info in the comments fill in `COFACTOR_INV` value for g1 fill in `COFACTOR_INV` value for g2 * update module description author information 2-adicity of the scalar field * update changelog * remove trailing comma * remove todo * 2nd loop count is x^3 - x^2 - x * Revert "2nd loop count is x^3 - x^2 - x" This reverts commit 2b323db3baff06a6077fd7505ff489fa31be7282. * fix comment regarding non-residue * first loop count should be X * 1. Generic BW6 params added to BW6-761 2. Curve specific hard part of the final exp moved from algebra * 1. Generic BW6 params added to BW6-767 2. Miller loop params changed to the "unoptimized" version * cargo fmt * changelog updated * X_MINUS_1_DIV_3 added to BW6Config * imports fixed --------- Co-authored-by: mmagician <marcin.gorny.94@protonmail.com>
