[Deno][deno] module to translate Worker's system of messages into

[`ReadableStream`][readablestream] and

[`WritableStream`][writablestream].

## Example

#### Server

```typescript

import {

  readableStreamFromWorker,

  writableStreamFromWorker,

} from "@lambdalisue/workerio";

const decoder = new TextDecoder();

const encoder = new TextEncoder();

const worker = new Worker(new URL("./worker.ts", import.meta.url).href, {

  type: "module",

});

const reader = readableStreamFromWorker(worker);

const writer = writableStreamFromWorker(worker);

const w = writer.getWriter();

await w.write(encoder.encode("Hello"));

await w.write(encoder.encode("World"));

w.releaseLock();

for await (const data of reader) {

  const text = decoder.decode(data);

  console.log(text);

}

```

#### Worker

```typescript

/// 

/// 

import {

  readableStreamFromWorker,

  writableStreamFromWorker,

} from "@lambdalisue/workerio";

const decoder = new TextDecoder();

const encoder = new TextEncoder();

async function main(): Promise {

  const reader = readableStreamFromWorker(self);

  const writer = writableStreamFromWorker(self);

  const w = writer.getWriter();

  for await (const data of reader) {

    const text = decoder.decode(data);

    await w.write(encoder.encode(`!!! ${text} !!!`));

  }

  w.releaseLock();

}

main().catch((e) => console.error(e));

```
