fix(hash-stream-node): do not create copy of file stream

[trivikr]

Issue

Fixes: #3378

Description

Do not create a copy of file stream.

Testing

Integration testing

Verified that following operations are successful:

PutObject file without checksum

import { S3 } from "../aws-sdk-js-v3/clients/client-s3/dist-cjs/index.js";
import { createReadStream } from "fs";

const region = "us-west-2";
const client = new S3({ region });

// File created with command "(for i in {1..1000}; do echo $i "hello world"; done) > hello-world.txt"
const fileName = "hello-world.txt";
const readableStream = createReadStream(fileName);

const Bucket = "aws-sdk-js-trivikr";
const Key = fileName;
const Body = readableStream;

await client.putObject({ Bucket, Key, Body });

PutObject file with checksum

import { S3 } from "../aws-sdk-js-v3/clients/client-s3/dist-cjs/index.js";
import { createReadStream } from "fs";

const region = "us-west-2";
const client = new S3({ region });

// File created with command "(for i in {1..1000}; do echo $i "hello world"; done) > hello-world.txt"
const fileName = "hello-world.txt";
const readableStream = createReadStream(fileName);

const Bucket = "aws-sdk-js-trivikr";
const Key = fileName;
const Body = readableStream;
const ChecksumAlgorithm = "CRC32";

await client.putObject({ Bucket, Key, Body, ChecksumAlgorithm });

GetObject file with checksum

import { S3 } from "../aws-sdk-js-v3/clients/client-s3/dist-cjs/index.js";
import { createWriteStream } from "fs";

const region = "us-west-2";
const client = new S3({ region });

const fileName = "hello-world.txt";
const Bucket = "aws-sdk-js-trivikr-flexible-checksums-testing";
const Key = fileName;
const ChecksumMode = "ENABLED";

const { Body } = await client.getObject({ Bucket, Key, ChecksumMode });
const writeStream = createWriteStream("./hello-world-copy.txt");
Body.pipe(writeStream);

Diff is empty:

$ diff hello-world.txt hello-world-copy.txt

Additional context

The issue with fd.createReadStream will be tracked in #3377
