Custom interpolations in /keyframes

[Picalines]

In current version of the mod you can only specify the value for keyframes, but can't customize interpolation between them - linear interpolation will be used by default

Ideally, you should be able to configure interpolation in /keyframes using the Keyframe struct fields:

{
  "properties": {
    "transform.position.x": {
      "keyframes": {
        "1": {
          "value": 0,
          "inWeight": 0.333,
          "inTangent": 5
        },
      }
    }
  }
}
