Generate JSON file of events

[mukundbhudia]

Need to generate a JSON file of events stored in the calendar

This will be later used to populate a front-end.

For the .env the variable CALENDAR_JSON_SAVE_PATH can be used to determine whether or not to generate the file.

And example output could be:
