[noise] JavaScript (WebAssembly) port of noise-c implementation

[Nazar Mokrynskyi]

Hi folks,

Have some good news about WebAssembly port of noise-c!

I've worked on test vectors today and now noise-c.wasm passes all of the vectors included in noise-c repository, so in terms of spec compliance (v30 according to noise-c's website at the moment) it should be on par with noise-c.

While working on test vectors only single minor issue was found, so I've published version 0.1.0 on NPM: https://www.npmjs.com/package/noise-c.wasm

Performance comparison would be interesting indeed, I can do the work on my side in JavaScript if someone can write benchmark in C or any other language.

Sincerely, Nazar Mokrynskyi
