Override input element and control initial months displayed

[benfoster]

Hi,

Thanks for your work on this component. I have a few questions regarding its usage:

1. ~Is it possible to override the tailwind styles applied to the date picker input element so that we can match our other input styles (border colors etc.). The theme alone is not sufficient for this. Alternatively can we provide our own input element?~
2. Can I set the default display months? We're using the component to select dates in the past so ideally I want to show the previous and current month by default.
3. Can I hide the clear button and always show the calendar icon?
4. How can I make use of dayjs advancedFormat?
