FF7 Rebirth - remove save slot limit

[Raffy55]

There are people like me who like doing lots of saves just before epic or beautiful moments in the game so we can just load it up and go through those moments again right there and then. Rebirth has a lot of those moments for me and the save slot limit is killing me. We have chapter select, but then you would have to go through everything that chapter has if that moment you wanna replay is by the middle or the end of the chapter which is a big hassle especially if that chapter has lots of dialogues and a long dungeon.
