Convert all values in a column to strings

If converting the _value column to string types, use toString(). If converting columns other than _value, use map() to iterate over each row and string() to convert a column value to a string type.

    |> map(fn: (r) => ({r with exampleCol: string(v: r.exampleCol)}))
