Additional columns

Running the add_columns function on a dataset adds the following columns to native CLDF components:

{
    "ExampleTable": [
        {
            "name": "Text_ID",
            "required": false,
            "dc:description": "The larger discourse context in which this record was uttered.",
            "datatype": "string"
        },
        {
            "name": "Sentence_Number",
            "required": false,
            "dc:description": "The positions of this record in the text.",
