Import categorization labels into a categorization project

Records are streamed in as new-line separated categorization dataset actions (see Modify Records in a Dataset) that are in the format:

{
  "action": "CREATE|DELETE",
  "recordId": "...",
  "record": {
    "verified": {
      "category": {
        "categoryId": "resourceId of category, e.g.unify://my-instance/v1/projects/1/taxonomy/categories/3",
        "path": [ /* string array representing the path of the category */ ],
        "reason": "optional description of why this categorization was verified"
      }
    }
  }
}

Note that each JSON object must be on a single line. Showing a pretty-printed version here for the purposes of readability.
