[FEATURE]: Select Disabled Dates When in "multiple-range" Mode

[GibzClt]

Forked from #369

I'm not sure if this feature already exists, at least I'm not able to find it in the docs.
I have a scenario of a trip days calendar where some dates are disabled because no flights are available on those particular days. When I keep the mode as 'multiple-range" and select a range which includes disabled dates (but the start data and end date are not disabled), the selection looks like a "multiple" select rather than a "multiple-range".
Ideally when we only get the edge dates, the selection should show the disabled dates as selected too if it is within the range

Before selection (to show the disabled dates)

After selecting a range which includes disabled dates

Also attaching a codepen for demonstrating the issue

I'm not sure if it's related or not, but it reminds me of the issue #329
