* split modular inversion in its own file
* Stash fast GCD inversion https://eprint.iacr.org/2020/972.pdf
* Stash Pornin's bingcd -> issue with inner modular reduction
* Implement Bernstein-Yang inversion
* Avoid Nim checks on signed integers (32-bit runtime issue)
* cleanup: remove old inversion impls
* cleanup: static moduli, move div2
* small comments (skip ci)
* comment cleanup (skip ci)
* fix total iterations on 32-bit
* Add batch conversion to affine coordinates using simultaneous inversion trick
* fix conditional setZero and batchAffine conversion
* cleanup unneeded branches following affine conversion unification
* Fix batchAffine with zero inputs and add fuzz failure to test suite
* Add Fp, Fp2, Fp6 support for BW6-761
* Add G1 for BW6-761
* Prepare to support G2 twists on the same field as G1
* Remove a useless dependent type for lines
* Implement G2 for BW6-761
* Fix Line leftover
* 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
