Endomorphism G2 (#79) 
* Clear cofactor in BN254 G2 testgen and frobenius

* Implement G2 endomorphism acceleration in Sage

* Somewhat working accelerated scalar mul G2 (2.2x) faster
- OK for BN254_Snarks
- Some test failing for BLS12-381

* Fix negative miniscalars by adding an extra bit of encoding

* Cleanup accel params

* Small recoding optimizations

Sage scripts

This folder holds sage scripts:

  • either for automating curve configuration for example for computing the prime and order of BN or BLS curve families, for irreducible polynomials for extension fields.
  • for test vectors against a reference implementation.
