For date formatting, I suggest we simply accept a Java date format string: https://docs.oracle.com/javase/10/docs/api/java/text/SimpleDateFormat.html
We need to be able to handle nanoseconds, which the Intl.DateTimeFormat JS library does not account for.
We'll need to convert the date object to a format the client can understand (similar to date_picker) but we'll need to ensure we keep the nanosecond bit (so probably mapping to DateWrapper).

So for the format_options argument, we will accept NumberFormatOptions (which we've defined as NumberFieldFormatOptions) and DateFormatOptions (which we could define as something like { date_format: DateFormatJavaString }, and DateFormatJavaString is just a str with some docs linking to the Java docs: https://docs.oracle.com/javase/10/docs/api/java/text/SimpleDateFormat.html

@dsmmcken does this sound reasonable?
