Merge sfMaps and sfCollectionMaps?

[Xymanek]

e.g.

    "sfMaps": [
        "Obj_SupplyExtraction_CI"
    ],
    "sfCollectionMaps": [
        {
            "name": "StrategyCollection_CI",
            "packages": [
                "GeoscapeMesh_CI",
                "UILibrary_CI_ChainPreview",
                "UILibrary_CovertInfiltration"
            ]
        }
    ]

could become

    "sfMaps": [
        "Obj_SupplyExtraction_CI",
        {
            "name": "StrategyCollection_CI",
            "packages": [
                "GeoscapeMesh_CI",
                "UILibrary_CI_ChainPreview",
                "UILibrary_CovertInfiltration"
            ]
        }
    ]

(short form and long form)

No longer relevant with the change to DLC cook (#46)
