Schedule importer from Zaxidfest site to Google calendar

It's a quick and dirty solution to add all show schedule to a new calendar in Google calendar.

What you need is to:

1. Build a project
2. Create credentials.json file for a desktop all. https://developers.google.com/workspace/guides/create-credentials
3. Run
4. Hope for the best

This program will destoy all events in calendar called "ZaxidFest_auto". So modify a code if you have one.

I hope their site engine will remain the same for 2022 festival)
