/**
 * Helper to abort upload requests if there has not been any progress for `timeout` ms.
 * Create an instance using `timer = new ProgressTimeout(10000, onTimeout)`
 * Call `timer.progress()` to signal that there has been progress of any kind.
 * Call `timer.done()` when the upload has completed.
