CI: enable GMP tests on Windows and Linux 32-bit and fix caching (#204) 
* Try to compile with GMP on windows and 32-bit linux

* remove leftover msys shell

* Don't use GMP Mersenne Twister, bad randomness and untested Nim wrapper

* properly cache nim

* fix path after cache

* run pacman in msys2 env

* rework msys2 ... again

* shell compat for file clearing

* shell compat try-again for file clearing

* force bash for clearing parallel builds on windows

* Use nimscript directly (why didn't it work last time?)

* Avoid IO redirection to support any shell

* Avoid IO redirection v2 to support any shell

* add debug data

* add debug again

* Introduce pararun, a parallel test runner to remove need of GNU parallel

* pararun: style

Self-contained bindings generation (#196) 
* First draft at bindings generation

* finite field bindings PoC

* support openarray, export NimMain

* PoC extension fields and elliptic curve bindings

* Pasta

* expose more bindings, remove nimZeroMem, remove tracer when unused, codegen name_mangling`gensym issue

* workaround bad C gensym codegen with {.inline.} pragma in non-dirty template nested in generic proc instantiated by template
