A description of the changes proposed in the Pull Request

• Add functionality to check if the provided manifest outputs are correct
• There are 2 cases to test:
• When you provide manifest file path: npm run if-check — -m ./manifests/outputs/manifest.yaml. If the outputs are the same as the generated manifest file, it should print Files match! or 

  Files do not match! tree.children.child.outputs.0.cpu/energy source: 0.08333333333333333 target: 0.1
• When you provide a directory path where placed manifests files are: npm run if-check — -d ./manifests/output/. It should print every file name with the execution result

sgtm, but could you remove the < and > characters wrapping tyhe filename in the response message?

i.e. like this:

if-check could not verify teads-curve.yml

not this

if-check could not verify <teads-curve.yml>

When folder doesn't contain any yamls, only checking message is shown.
Expected Behavior: Folder is empty, or similar message.
