FileUploadOptions - timeout

Hi there,

Would you guys be able to reinstate this PR below?
https://github.com/apache/cordova-plugin-file-transfer/pull/156

It'd be great if I could set the timeout for file uploads.
Perhaps an extra property to FileUploadOptions?

FileUploadOptions.timeout = (90*1000);
The timeout variable is to be specified in milliseconds.

I have an app where users might try to upload large files on the 3G/4G network.
Thank you very much in advance.

Cheers 😄 👍

Review the previously requested PR #156 and the FileUploadOptions API mentioned in the issue. Determine how upload timeouts are handled, then verify that a timeout can be configured in milliseconds and applies to large-file uploads.
