When setting date on a Calendar that has an offset week start, range starts on incorrect day.

[Saikred]

When Calenday is set to select a week range, with the week starting on Monday,
pickWeeks: true, multiple: true, week: 1, //Monday

using the method to set the date causes it to set the range Sunday to Saturday, instead of Monday to Sunday as the Calendar does when you are otherwise clicking dates.
$('.calendar').pignoseCalendar('set', '2021-11-08')
