Increase co-op numbers

[Coolsvilleman]

My friends and I got into this game surprisingly, paid for the full version. Overall decent and loving the patches. Sadly the four player co-op is a real disappointment when you get to a larger store. Would be great if it was 8 players like another grocery store stocking shelf simulator `Supermarket simulator`. Friends in the group literally not buying the game because we cannot all play together at once so we have to go to the other game.

Also bonus points if we can join session live rather than quitting to allow a new player to join. Though this is really a secondary ask to the first.
