Allow passing additionalTransforms to registerTransforms

[jorenbroekema]

registerTransforms(StyleDictionary, { additionalTransforms: ['name/cti/kebab'] });

Since you can't combine transformGroup + transforms, it's not really easy to do it yourself... you would need to resort to:

{
  "platforms": {
    "css": {
      "transforms": [
        "ts/descriptionToComment",
        "ts/resolveMath",
        "ts/size/px",
        "ts/size/letterspacing",
        "ts/size/lineheight",
        "ts/type/fontWeight",
        "ts/color/hexrgba",
        "ts/color/modifiers",
        "ts/typography/css/shorthand",
        "ts/shadow/shorthand",
        "name/cti/kebab"
      ],
      "buildPath": "build/css/",
      "files": [
        {
          "destination": "_variables.css",
          "format": "css/variables"
        }
      ]
    }
  }
}

Handled by #175 , at least for casing. For changing transforms in a different way, refer to https://github.com/tokens-studio/sd-transforms#custom-transform-group
