Add the current elo#29

Elo plays a big part in match making in AoE, like in lots of game for that matter.

It’s not possible to get the elo while playing the game, which I always found super weird.

What could be added in capture age could be the current elo (if any) of the players in the game.

This would likely be the elo at the time of rewatching the game (because I suspect AoE 2 does not store it in the replay) and I think that’s totally fine.

Any updates on this?
