restrict calendar to weeks-range

[prabu-ssb]

Describe the solution you'd like
We have a requirement for a displaying just 2-3 weeks, instead of the whole month view. Say, only week 43 and 44.
Preferably be able to toggle this view with the default calendar view programmatically.

Describe alternatives you've considered
I tried using a combination of modifiers and renderWeek, but the rows for the week are displayed with empty cells.
Not sure how I can get DayPicker-Week--.* specified.

Additional context
It would also be sufficient if we could have something like a weeksModifier which we could use to control display of weeks outside the required range.
