Pipelines should create unique instances for nodes that are re-used
**Description**
When a node is re-used in a Pipeline, it may be evaluated more than once with different coordinates. The pipeline should still evaluate correctly, but debugging becomes unreliable. All of the nodes in a Pipeline should be unique instances.

**Describe the solution you'd like**
Nodes should be copied if necessary during Pipeline instantiation.

**Additional context**
We may additionally want to ensure that Algorithms and Compositors also don't re-use nodes, either throwing an exception (or warning) or just copying when necessary.
