Dependency Graphs (#2308)

* Further fixes to the example code.

* Bumped dependencies.

* Fixed Debouncer example code.

* Some more cleanup.

* Black's opinion.

* Run with pyVHDLModel dev-branch.

* Fixed imports for Name.

* Fixed test case.

* Added a formatter to write dependency graphs and hierarchy as graphml.

* Improved GraphML formatting.

* Write compile order graph.

* Computing compile order.

* Bumped dependencies.

* Black's opinion.

* Fixed incorrect dependency.
