Optimize Miller Loop and prepare Multi-pairing (#159)
* Pairing with affine: align API to BLST and Gurvy and common use-case.

* Implement multi-pairing / aggregate verif for BLS12-381 (+2% pairing perf)

* Generalize the optimized miller loop for single pairing

* Immplement the miller loop addchain for BLS12-377

* Miller addition chain for BN254-Nogami

* no Miller adchain for BN254-Snarks

* Update the line test with new tower https://github.com/mratsim/constantine/pull/153

* Somewhat sparse for Fp2 M-Twist

* Implement line by line multiplication for Fp12 D-Twist

* Somewhat sparse Mul for Fp12 D-Twist

* Finish the sparse and somewhat sparse multiplications

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
