store input element in DatePicker instance

[ebrensi]

@luizbills this is why I'm here too. If I instantiate two TinyDatePickers via a class selector like

const datePicker = TinyDatePicker(".datepick", {
      mode: 'dp-below',
});

and attach a listener

 datePicker.on("statechange", (e, picker) => {
     const state = picker.state,
              date = state.selectedDate;
     // I need to know which of two datepickers I am getting called from.
 });

Is there already a way to do this?
