GDTF import simplification: Intensity/ColorIntensity

[kengruven]

For GDTF imports, it's extremely common to see capabilities that look like this:

    "Dim": {
      "highlightValue": 255,
      "capabilities": [
        {
          "dmxRange": [0, 0],
          "type": "Intensity",
          "brightnessStart": 0,
          "brightnessEnd": 1,
          "comment": "Closed"
        },
        {
          "dmxRange": [1, 254],
          "type": "Intensity",
          "brightnessStart": 0,
          "brightnessEnd": 1
        },
        {
          "dmxRange": [255, 255],
          "type": "Intensity",
          "brightnessStart": 0,
          "brightnessEnd": 1,
          "comment": "Open"
        }
      ]
    }

I suspect that this structure is idiomatic in GDTF, but coming from OFL it just looks like a really convoluted way to write:

    "Dim": {
      "capability": {
        "type": "Intensity"
      }
    }

(And similarly for ColorIntensity channels.)

It would be great if we could identify this pattern in the GDTF importer, and rewrite it in the simpler form automatically.
