Fast modular inversion (#172)
* split modular inversion in its own file

* Stash fast GCD inversion https://eprint.iacr.org/2020/972.pdf

* Stash Pornin's bingcd -> issue with inner modular reduction

* Implement Bernstein-Yang inversion

* Avoid Nim checks on signed integers (32-bit runtime issue)

* cleanup: remove old inversion impls

* cleanup: static moduli, move div2

* small comments (skip ci)

* comment cleanup (skip ci)

* fix total iterations on 32-bit

* Add batch conversion to affine coordinates using simultaneous inversion trick

* fix conditional setZero and batchAffine conversion

* cleanup unneeded branches following affine conversion unification

* Fix batchAffine with zero inputs and add fuzz failure to test suite
