Event ( BBB ) calendar for Lichess Team

[TBestLittleHelper]

Lichess hosts and puts on a lots of events. We would like to do our best to avoid event's occupying the same timeslots ( as often we could suggest to the organizer moving the time or date). A calendar would allow the Lichess team better overview and less reliant on individuals as the entire team could catch conflicts.

• [ ] Show all events from https://lichess.org/event/manager
• [ ] Show all events from https://lichess.org/tournament/manager
• [ ] Important events from https://lichess.org/broadcast

As this is for managing the Homepage, in all cases we care about the respective " Hours on homepage " data. For broadcasts this is when Rounds start ( we don't know when a round ends, so maybe just add a fixed amount of hours based on the Broadcast tier? ). I think it's important to have Broadcasts in the calendar, as often they generate manual BBB's on short notice. For example if a streamer covers the event.
