"""Create a fake CancelHook used instead of a dependency, it cannot be used to cancel!
Certain actions require a CancelHook to be supplied if called directly. The only method
we use from the LabThings CancelHook is ``sleep()``. The CanceHook ``sleep()`` works
exactly like ``time.sleep()`` except with raise an ``InvocationCancelledError`` if the
server receives a cancellation request.
This is just an object with a sleep method.
