Feature proposal: battle royale mode

[Graeme22]

It would be fun to add a new gamemode, similar to geoguessr's where the furthest away player gets eliminated each round until a single player remains. Should be very simple to implement given all the necessary logic is already there!

I can contribute a PR if desired!

This is a great idea! It might be easier to add this in parties first, and then if it's popular enough roll it out as a public mode. I will try to see if I can implement it along with the next update
