Workflow run terms for parameter connections

[simleo]

See ResearchObject/workflow-run-crate#25.

The idea is to use them like this:

{
    "@id": "packed.cwl",
    "@type": ["File", "SoftwareSourceCode", "ComputationalWorkflow", "HowTo"],
    "hasPart": [
        {"@id": "packed.cwl#revtool.cwl"},
        {"@id": "packed.cwl#sorttool.cwl"}
    ],
    "input": [
        {"@id": "packed.cwl#main/input"},
        {"@id": "packed.cwl#main/reverse_sort"}
    ],
    "output": [
        {"@id": "packed.cwl#main/output"}
    ],
    "connection": [
        {"@id": "#pc-1"},
        ...
    ],
    ...
},
{
    "@id": "packed.cwl#revtool.cwl",
    "@type": "SoftwareApplication",
    "input": [
        {"@id": "packed.cwl#revtool.cwl/input"}
    ],
    "name": "revtool.cwl",
    "output": [
        {"@id": "packed.cwl#revtool.cwl/output"}
    ]
},
{
    "@id": "packed.cwl#main/input",
    "@type": "FormalParameter",
    "additionalType": "File"
},
{
    "@id": "packed.cwl#revtool.cwl/input",
    "@type": "FormalParameter",
    "additionalType": "File"
},
{
    "@id": "#pc-1",
    "@type": "ParameterConnection",
    "sourceParameter": {"@id": "packed.cwl#main/input"},
    "targetParameter": {"@id": "packed.cwl#revtool.cwl/input"}
}

What about N-to-1 and 1-to-N connections?
There should be a single ParameterConnection object per pair or the sourceParameter and targetParameter can take list values?

They can take list values
