fix(wasm): compilable and updated some of the bindings

[berendsliedrecht]

Did some local testing and ed25519sha512 and bls seem to work.

import { Ed25519Sha512 } from "ursa";
import assert from "assert";

// Test vectors from ursa/libursa/src/signatures/ed25519.rs

const message = new TextEncoder().encode(
  "This is a dummy message for use with tests"
);

const signature = Buffer.from(
  "451b5b8e8725321541954997781de51f4142e4a56bab68d24f6a6b92615de5eefb74134138315859a32c7cf5fe5a488bc545e2e08e5eedfd1fb10188d532d808",
  "hex"
);

const publicKey = Buffer.from(
  "27c96646f2d4632d4fc241f84cbc427fbc3ecaa95becba55088d6c7b81fc5bbf",
  "hex"
);

assert(Ed25519Sha512.verify(message, signature, publicKey));

bls has some issues, maybe intentional, with dropping values (see g1 and g2).

import assert from "assert";
import { Bls, Generator, SignKey, VerKey } from "ursa";

const msg = new Uint8Array([1, 1, 1]);

const seed = new Uint8Array(32);
const b = new Generator().toBytes();

// Creating of the same two generators as `Bls.sign` drops one and `Bls.verify` as well.
const g1 = Generator.fromBytes(b);
const g2 = Generator.fromBytes(b);

const signKey = SignKey.fromSeed(seed);
const signKey2 = SignKey.fromSeed(seed);

const verKey = new VerKey(g1, signKey);
const signature = Bls.sign(msg, signKey2);

assert(Bls.verify(msg, signature, verKey, g2));

Also, I was curious what the intention of the wasmprivatekey and wasmpublickey were. I assume that you do not deal with the keys themselves in the JS side.

In principle it looks good. Let me know once you've addressed the comments, and I'll approve.

All comments should be resolved.
