Function toArrayBuffer

toArrayBuffer(readableStream): Promise<ArrayBuffer>
Converts a ReadableStream of Uint8Arrays to an ArrayBuffer. Works the same as Response.arrayBuffer.
Parameters
- readableStream: ReadableStream<Uint8Array>
  A ReadableStream of Uint8Arrays to convert into an ArrayBuffer.
Returns Promise<ArrayBuffer>
A promise that resolves with the ArrayBuffer containing all the data from the stream.
Example: Basic usage
```
import { toArrayBuffer } from "@std/streams/to-array-buffer";
import { assertEquals } from "@std/assert";

const stream = ReadableStream.from([
  new Uint8Array([1, 2]),
  new Uint8Array([3, 4, 5]),
]);
const buf = await toArrayBuffer(stream);
assertEquals(buf.byteLength, 5);
```
