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

BLS12-377 (#91)
* add Sage for constant time tonelli shanks

* Fused sqrt and invsqrt via Tonelli Shanks

* isolate sqrt in their own folder

* Implement constant-time Tonelli Shanks for any prime

* Implement Fp2 sqrt for any non-residue

* Add tests for BLS12_377

* Lattice decomposition script for BLS12_377 G1

* BLS12-377 G1 GLV ok, G2 GLV issue

* Proper endomorphism acceleration support for BLS12-377

* Add naive pairing support for BLS12-377

* Activate more bench for BLS12-377

* Fix MSB computation

* Optimize final exponentiation + add benches
