moved config to yaml, remove unused tests

[fritjof-b]

This is a big PR, moving the configuration to YAML in the root of the project. This config then gets copied when you create a new project using --newProject. The config file itself might need some refinement.

Breaking: If you're currently using a config.py, you need to translate it to <project_name>_config.yaml, and store it in the same location as your previous python configuration.

For reviewers: Please check out the branch and run your models, and plotting before approving.

Starting a checklist to see what works and not:
works

• CFD animation with updated config file
• CMS Project v1 with updated config file

doesn't work

• config file needs input_path: "" which points to the workspace/<workspace_name>/data/<workspace_name_data>.npz file

• CDF still animation (not sure if this one worked before)
