0.5.0

This version simplifies error handling:

• The getSnapshot() method now returns an instance of the WorkflowMachineSnapshot class, which includes three new methods: isFinished(), isFailed(), and isInterrupted(). Additionally, you can retrieve the id of the last executing step by calling the tryGetCurrentStepId() method.
• The unhandledError property of the snapshot class is always an instance of the MachineUnhandledError class.
