Is your feature request related to a problem? Please describe.

The current types for onUploadProgress and onDownloadProgress use any as the type for the event passed to these callbacks. However, the documentation for the Request Config describes this event as the "native progress event".

Describe the solution you'd like

Change the type of the event passed to the progress event callbacks to the native ProgressEvent type.

Describe alternatives you've considered

If I have misunderstood the above documentation, I would recommend creating custom, exported types for these progress events to remove the use of the any type.
