Add duration parameter to run method in DataStream

I wanted to create a unit test where I track an instrument for a period of time and then stop it to go and check if the data has been processed correctly. However I could only see the keyboard interrupt and I think it would be good to have a parameter where you can allow the instrument to run for a certain amount of time. This could then be used for syncing up with opening hours of the instrument so you're not unnecessarily running a script.

Describe the solution you'd like.

A simple parameter in the run method that allows you to enter a duration, this could be in the form of a datetime time delta object. You then start two tasks running with the asyncio library, one being the data collection and the other being a timer to check if the duration has been exceeded. The two tasks will then return whichever one finishes first which in this case will be the timer as the other task loops indefinitely.

Describe an alternate solution.
