FpDbl revisited (#144) - 7% perf improvement everywhere, up to 30% in double-width primitives
* reorg mul -> limbs_double_width, ConstantineASM CttASM

* Implement squaring specialized scalar path (22% faster than mul)

* Implement "portable" assembly for squaring

* stash part of the changes

* Reorg montgomery reduction - prepare to introduce Comba optimization

* Implement comba Montgomery reduce (but it's slower!)

* rename t -> a

* 30% performance improvement by avoiding toOpenArray!

* variable renaming

* Fix 32-bit imports

* slightly better assembly for sub2x

* There is an annoying bottleneck

* use out-of-place Fp assembly instead of in-place

* diffAlias is unneeded now

* cosmetic

* speedup fpDbl sub by 20%

* Fix Fp2 -> Fp6 -> Fp12 towering. It seems 5% faster

Sage constants & tests codegen (#101)
* Implement a Sage codegenerator for frobenius constants

* Sage codegen for pairings

* Autogen of endomorphism acceleration constants

* The autogen fixed a copy-paste bug in lattice decomposition. We can use conditional negation now and save an add+dbl in scalar mul

* small fixes

* sage code for square root bls12-377 is not old

* readme updates

* Provide test suggestions for derive_frobenius

* indentation + add equation form to sage

* Sage test vector generator

* Use the json vectors
- includes type system workaround: generic sandwich https://github.com/nim-lang/Nim/issues/11225
- converting NimNode to typedesc: https://github.com/nim-lang/Nim/issues/6785

* Delete old sage code

* Install nim-serialization and nim-json-serialization in CI

* CI nimble install force yes

Assembly backend (#69)
* Proof-of-Concept Assembly code generator

* Tag inline per procedure so we can easily track the tradeoff on tower fields

* Implement Assembly for modular addition (but very curious off-by-one)

* Fix off-by one for moduli with non msb set

* Stash (super fast) alternative but still off by carry

* Fix GCC optimizing ASM away

* Save 1 register to allow compiling for BLS12-381 (in the GMP test)

* The compiler cannot find enough registers if the ASM file is not compiled with -O3

* Add modsub

* Add field negation

* Implement no-carry Assembly optimized field multiplication

* Expose UseX86ASM to the EC benchmark

* omit frame pointer to save registers instead of hardcoding -O3. Also ensure early clobber constraints for Clang

* Prepare for assembly fallback

* Implement fallback for CPU that don't support ADX and BMI2

* Add CPU runtime detection

* Update README closes #66

* Remove commented out code
