Can't use a file stream

[guoh27]

const readStream = fs.createReadStream(inFile)
const writeStream = fs.createWriteStream(file)
const bandwidthThrottleGroup = createBandwidthThrottleGroup({
	bytesPerSecond: 500000
})
const throttleStream = bandwidthThrottleGroup.createBandwidthThrottle(500000)
read.pipe(throttleStream).pipe(writeStream)

will always RangeError: offset is out of bounds.
