Continue after event ("wait for event")

Inside your run function it would be useful to be able to pause execution until something external has happened.

We had a feature called "wait for event" in v2 that allowed you to do this. You could then send an event from your own code and the run would continue where it left off.

An example might be for an application process where the application needs to go through an approval step e.g. an AML check.

There would be a timeout of how long it would wait, with a default.
