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

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

5.3x faster test suite. 
The running time of the test suite has increased significantly with:
- new tests (for example scalar mul implementations)
- new tests that stresses the whole stack/tower
- x3 randomizers for fuzzing
- new CI and platforms: Total 16x runs per commit

This would let all tests take less than 10 min on CI even non-parallelized one like on Windows.

Fuzzing campaign fixes (#58) 
* Add test case for #30 - Euler's criterion doesn't return 1 for a square

* Detect #42 in the test suite

* Detect #43 in the test suite

* comment in sqrt tests

* Add #67 to the anti-regression suite

* Add #61 to the anti-regression suite

* Add #62 to anti-regression suite

* Add #60 to the anti-regression suite

* Add #64 to the test suite

* Add #65 - case 1

* Add #65 case 2

* Add #65 case 3

* Add debug check to isSquare/Euler's Criterion/Legendre Symbol

* Make sure our primitives are correct

* For now deactivate montySquare CIOS fix #61 #62

* Narrow down #42 and #43 to powinv on 32-bit

* Detect #42 #43 at the fast squaring level

* More #42, #43 tests, Use multiplication instead of squaring as a temporary workaround, see https://github.com/mratsim/constantine/issues/68

* Prevent regression of #67 now that squaring is "fixed"

* Add libsecp256k1 skewed RNG that found a CVE in OpenSSL

* Add initial skewed RNGs tests to finite fields

* Add Fp towers skewed tests

* Add ellptic curve skewed tests
