Manually set `selectedStartDate` and scroll to month

[SMJ93]

First of all, awesome library! So easy to setup and use!! Thank you 😄

We need to add some functionality so we can jump to the next quarter (a few months in advance). We can set the selectedStartDate to a value which updates the calendar value as expected, but it doesn't scroll to the correct month.

E.g. I may be in June and click next quarter, it selects the 1st of September, but doesn't scroll to the September month.

Thanks!

Try passing in the initialDate prop. The calendar will update as that prop changes. https://github.com/stephy/CalendarPicker#calendarpicker-props
