Naive pairings + Naive cofactor clearing (#82)
* 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
