Pass an array as defaultDate

Proposal

Currently there is no way to initialize a picker with multiple dates, or with a range already selected.

The defaultDate option should take in an string or an array, so as to have a range initialized, instead of having to add it manually afterwards.

Motivation and context

Having encountered the problem myself, initializing a calendar with a range is a pain.

If you set the input value to multiple dates. It should pick those up. Otherwise, if you want a programmatic way to set multiple values, this is how the picker does it.

I understand your use case. However, I don't think I could implement this right now.
