Branched Execution Order Control Node

[807502278]

Add a router node with multiple outputs,Execute subsequent branches in order from top to bottom.
Because when connecting multiple branches, it is impossible to control which branch runs first,
A simple example: Image connects two save nodes and cannot control which one saves first,
Of course, the actual situation will not be so simple. For example, I hope a fast running branch will produce results first.
