Location and Scaling for Logos on per-game basis

Feature Description

I would like to be able to replicate how Steam locates and scales logos for different games in Playnite. Like for example for Factorio the logo is at the center, and is kinda big, whereas for Monster Hunter: Rise it's at the bottom left, and feels a bit smaller. There's some games where in Playnite the logo is simply at the wrong location so the alternative is usually to simply not use the "logo" and just edit the background with the logo at the right location, which is quite a time investment if you have too many games.
