* Updates the closing times for each room on the daily grid.
* IMPORTANT: This function is called every time the content on the page changes eg: Due to a scroll event
*
* This is necessary since the website always fetches the schedules dynamically from the server as you scroll down the page.
* The website also destroys every schedule that is not currently in view and has to re-fetch it again every time you scroll up or down.
*
* As a consequence, we cannot extract all the closing times at one go, and this function has to be called every time
* the calendar view changes and then extract only the currently visible room schedules.
* We trigger functions on the changed elements using the MutationObserver() API.
*
* We accumulate the changes into window.closing_times object and then keep track of whether or not we have completed
* extraction by using the boolean flag window.all_rooms_done, which is set when the length of window.closing_times equals
* the total number of rooms available on the page as shown by the webpage on the bottom right.
*
* Once we have extracted closing times of all the rooms we need, we display the download CSV button to export it.
