[feature request]: best score ever

Hi, the profile page on the left shows the current score for different chess variants, and the ranking. I suggest also adding the best score ever achieved for that player in that variant. If too crowded, the best score could be displayed instead of the ranking, I find that more interesting for most users. Thanks for consideration.

PS: apologies, I meant "best rating" ever achieved for that chess variant, not best score. Thanks.
