Progress events not fired on PUT upload

I'm working with capacitor/file-transfer and not getting progress events on large (PUT) uploads. I think the reason is the progress event not emitting until the status code is 200+ in this code , perhaps this is a guard for downloads?

```
func urlSession(_ session: URLSession, task: URLSessionTask,
didSendBodyData bytesSent: Int64, totalBytesSent: Int64,
totalBytesExpectedToSend: Int64) {
self.totalBytesSent = Int(totalBytesSent)
let response = task.response as? HTTPURLResponse
let statusCode = response?.statusCode ?? 0
if (200...299).contains(statusCode) { // <-- THIS IS THE PROBLEM
publisher.sendProgress(...)
}
}

Let me know if you'd like more info or a PR for this?

Thanks
