Custom nodes to improve flow control and logic + several utilities to enhance capabilities

ControlFlowUtils

Allows you to end the current prompt execution on demand or depending on a given condition.

In order for this node to execute, it must be placed in the middle of an operation, so use the Input and Output channels as a Passthrough for any data you may wish to interrupt from being forwarded. To ensure this node runs at a specific and more predictable order, you may also connect the Output of any node of your choice to the Run_After Input of this node. This node should execute only after the previous node is done executing (lazy execution notwithstanding).

You may convert this node's Disable widget to an Input to make it a Condition that you can trigger with an [IF Selector] Node. If Disable is set to False, the current prompt will be halted prematurely when this node is executed.

Method will determine how the execution will be affected. Cancel Prompt will immediately interrupt execution everywhere when this node runs, whereas Block Execution will allow the execution to continue but will prevent any nodes connected to this one from running subsequently.

The Clear_Queue option will additionally clear your Execution Queue and set your Auto-Queue execution mode to Disabled, allowing you to cancel any pending processes.

The Alert_On_Trigger toggle will further raise an exception when the node interrupts the flow of execution, ensuring no other cached nodes continue executing after this one, giving you ample time to review your workflow's state after it has been halted.

Run_After is an unused optional parameter made available only to ensure this node executes after the node it is connected to.
