Check whether the given exception is considered a cancellation exception according to Temporal.

This is often used in a conditional of a catch clause to check whether a cancel occurred inside of a workflow. This can occur from asyncio.CancelledError or CancelledError or either ActivityError or ChildWorkflowError if either of those latter two have a CancelledError cause.

Parameters
exception:BaseExceptionException to check.
Returns
boolTrue if a cancelled exception, false if not.
