Added a timeout option to the Client

[esanchezm]

Hi everyone!

I just decided to create my own remote client desktop for qBittorrent and found your awesome library. I think it's lacking an option to setup the timeout as by default and according to requests library documentation:

Most requests to external servers should have a timeout attached, in case the server is not responding in a timely manner. By default, requests do not time out unless a timeout value is set explicitly. Without a timeout, your code may hang for minutes or more.

I'm interesting on a timeout to avoid my application to hang forever. I think it should be useful to define it in the Client constructor. Looking forward for your feedback

I finally got the time to check it out. Apologies for the long delay 😬
