Feature request: select multiple players on the challenge results screen

[ilya-zlobintsev]

It would be nice if it was possible to select multiple players on the results page, with all of the guesses displayed on the map at once so you can compare them. Similar to how GeoGuessr does it.

Taking a quick look at the code, LeaderboardCard and StreaksLeaderboard would need to be changed to accept an array or set of selected indexes, and ResultMap would need to accept multiple arrays of guesses with their associated avatars.
