Don't dump all in "backend" (#184) 
* backend -> math

* towers -> extension fields

* move ISA and compiler specific code out of math/

* fix export

Fr: Finite Field parametrized by the curve order (#115) 
* Introduce Fr type: finite field over curve order. Need workaround for https://github.com/nim-lang/Nim/issues/16774

* Split curve properties into core and derived

* Attach field properties to an instantiated field instead of the curve enum

* Workaround https://github.com/nim-lang/Nim/issues/14021, yet another "working with types in macros" is difficult https://github.com/nim-lang/RFCs/issues/44

* Implement finite field over prime order of a curve subgroup

* skip OpenSSL tests on windows

Implement BW6-761 Endomorphism acceleration (#104) 
* Implement BW6-761 GLV on G1 + Psi Untwist-Frobenius-Twist

* Fix frobenius constants for embedding degree != 12

* Fix test type/parsing issues

* Generalize frobenius map coefficient formula

* Fix Frobenius Psi generalization

* Don't confuse t and trace of frobenius + update scalarMul to use Frobenius on Fp Twist

* Fix ec_sage type definition

* fix decription [skip ci]

* update comment [skip ci]

* typo

* restore frobenius tests iterations

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
