[wasm] on windows fail to build cpp lib
secp256k1-sys v0.4.1 fails to build on windows system while on linux it passes.
It seems that cc lib that builds cpp inside rust requires ar to create static lib and can't find anything on windows. Maybe solution is to switch to clang and use llvm-ar but unsure how exactly to do that inside cc. Either way, build works on linux (still need to check if it runs) and that is good enough, for windows development we can omit this lib and do stuff without it and build the binary for npm on linux system.
full log:
