Incorrect annotation in `tatqa_dataset_dev.json`

[reganconnell]

Question "uid": "c91ad938-6ad1-4481-8f6b-43ccd2f69926" in the tatqa_dataset_dev.json appears to be annotated incorrectly. It's annotated as:

      {
        "uid": "c91ad938-6ad1-4481-8f6b-43ccd2f69926",
        "order": 4,
        "question": "What is the nominal difference for ROFE between F19 and F18?",
        "answer": 1.9,
        "derivation": "17.1 - 15.2 ",
        "answer_type": "arithmetic",
        "answer_from": "table",
        "rel_paragraphs": [],
        "req_comparison": false,
        "scale": "percent"
      },

when it should be the following based on the table data provided:

      {
...
        "answer": -1.9,
        "derivation": "15.2 - 17.1",
...
      },

Relevant table data for reference where you can see that the "ROFE (%)" "F19" value is "15.2", and "F18" is "17.1":

{
      "uid": "00addb09-bf31-4240-a351-bc4480a3cecc",
      "table": [
        [
          "",
          "F19",
          "F18 (3)",
          "",
          "CHANGE"
        ],
        ...
        [
          "ROFE (%)",
          "15.2",
          "17.1",
          "(190) bps",
          "(215) bps"
        ]
      ]
    },
