[Bug]: ChunkedArrayBufferStream throws RangeError when targetChunkSize is not an integer

[rseanhall]

What happened?

I'm trying to transcribe speech from a WAV file from the npm package of version 1.38.0.

    let sourceFile: File;
    // let user pick the file
    const audioConfig = AudioConfig.fromWavFileInput(sourceFile);
    let speechConfig: SpeechConfig;
    // initialize speechConfig
    const conversationTranscriber = new ConversationTranscriber(speechConfig, audioConfig);
    // subscribe to events in conversationTranscriber
    conversationTranscriber.startTranscribingAsync();

For this specific WAV file, it causes an error:
problemfile.zip

ERROR RangeError: offset is out of bounds

    at Uint8Array.set (<anonymous>)

After some investigating, the problem seems to be in the ChunkedArrayBufferStream constructor:

cognitive-services-speech-sdk-js/src/common/ChunkedArrayBufferStream.ts

Lines 12 to 16 in c12dc56

	public constructor(targetChunkSize: number, streamId?: string) {
	super(streamId);
	this.privTargetChunkSize = targetChunkSize;
	this.privNextBufferReadyBytes = 0;
	}

It's getting initialized with the targetChunkSize of 1102.5. This causes problems because it is used to setup byte arrays, which can't have fractional items.

Version

1.36.0 (Latest)
