Jetbookings: Add option to block days before/after bookings

[Marcy376]

Jetbookings should have a feature to block days before/after bookings to allow buffer time in between bookings.

This should be integrated into jetbookings and included in the woocommerce integration also.

For example, when a woocommerce product is booked, and if I set 3 days blocked before booking, and 3 days blocked after booking, the booking calender should have those dates disabled.

There is currently a code snippet for this HERE which is only working for booking for built on jetformbuilder and does not have any effect on the calender datepicker assigned before the "add to cart" button for jetbooking woocommerce products.
