Add example script showing how to perform a blocking pop from a list.

[simonprickett]

Add an example script that shows how to use the BLPOP command to block indefinitely until an element is pushed to a list, then returns that element and displays it with console.log.

Use the LPUSH command to push an element into the list, which should unblock your BLPOP call.

For this, you'll need to use the "isolated" option, see the documentation in the README here - this describes the scenario you'll need to implement when making this example.

Name your file blocking-list-pop.js (or .ts if you prefer TypeScript. Name the function containing your code blockingListPop and please pay attention to the guidelines for adding an example to ensure that your contribution can be merged.
