Custom date format for DatePickerWidgetAnnotation

Hi,

I am creating them programmatically, roughly like this:

const field = new Annotations.Forms.Field(fieldItem.Id, {
    value: fieldItem.Value // some value
});
const annot = new Annotations.DatePickerWidgetAnnotation(field);

// ... apply page/width/height/x/y here ...

 annotManager.addAnnotation(annot);
 annotManager.redrawAnnotation(annot);

Cheers, Luke.
