passing worker as blob

Closes #1

So it works... at least for an example from readme :D
But test fails. I think that is because ts compiler warnings.

import { parry } from "./mod.ts";

async function countSerial(limit: number): Promise<void> {
  for (let i = 0; i < limit; i++) {}
}

console.time("4x CountSerial");
await Promise.all([
  countSerial(1e9),
  countSerial(1e9),
  countSerial(1e9),
  countSerial(1e9),
]);
console.timeEnd("4x CountSerial");

const threads = [
  parry(countSerial),
  parry(countSerial),
  parry(countSerial),
  parry(countSerial),
];

console.time("4x CountParallel");
await Promise.all([
  threads[0](1e9),
  threads[1](1e9),
  threads[2](1e9),
  threads[3](1e9),
]);
console.timeEnd("4x CountParallel");

parry.close();

Gives as expected:

4x CountSerial: 2303ms
4x CountParallel: 658ms
