Read CWLs without storing them

[almanilsson]

          The file could be read without storing it I think. I assume that you will receive 1 workflow in CWL and you can verify and parse it without storing it locally, something similar to:

async def score_workflows(file: UploadFile = File(...)):
    # Read the contents of the uploaded file
    contents = await file.read()
    
    # Parse the YAML content as a CWL workflow (this tests whether the file is a YAML file)
    try:
        cwl_content = yaml.safe_load(contents)
    except yaml.YAMLError as e:
        return {"error": "Invalid YAML file", "details": str(e)}
    
    # Extract information from the CWL workflow
    extracted_info = extract_info_from_cwl(cwl_content)

pubmetric.workflows.parse_cwl currently takes a filepath and then opens them inside the method. Need to make this optional or change to take an open file.

The reason it does that is because cwl_utils.parsers' load_document_by_uri takes a filepath not a file.
