Add CI/CD Pipeline and Tests

[DRovara]

This pull request adds tests and a CI/CD pipeline to the project

Pipeline

The CI/CD pipeline is based on the MQT reusable workflows. The workflow files are heavily inspired by QCEC.

Tests

This pull request introduces a large number of tests, ranging from unit tests to end-to-end tests. They are run by the CI pipeline.

It includes the following test types:

• Python Tests
  • Tests for all individual Python bindings
  • Tests for all diagnosis methods and their interpretation in Python
  • Several end-to-end tests that simulate full code files and compare their measurement results and the number of encountered assertion failures
• C++ Tests
  • Tests of all utility functions (such as getting the exact position of an instruction in the code)
  • Tests of all diagnosis tools
  • Tests of data retrieval during debugging, including getting individual amplitudes, state vectors and classical values
  • Tests of simulation methods such as stepping through the code and using breakpoints
  • "custom code" tests that allow individual qasm code examples to be tested.

While the name for the project has not been finalised (mqt-debug, mqt-debugger, ...), some links may be incorrect.
