For example, `"parse": {"modified_on": "date"}` parses the `modified_on` field in each input record a Date value.
For `"date"`, we parse data based using Javascript's [`Date.parse()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/parse).
For Specific date formats can be provided (e.g., `{foo: 'date:"%m%d%Y"'}`), using the [d3-time-format syntax](https://github.com/d3/d3-time-format#locale_format).
