Make the timeout durations consistent. A default timeout had been added to the camera's take_exposure method, which was then being passed to the _poll_exposure. Previously _poll_exposure had a timeout=None default, so it would build a new timeout duration consisting of the exptime, readout time, and a "timeout" padding. This change just builds that default in take_exposure and passes it to _poll_exposure but also uses the value to control the blocking in take_exposure.
