Add right joystick quicknav for t16 map tab

Currently there is no function for right joystick when selecting a map, so I think we should be able to jump down to the actual map storage from map selecting. Right now you either have to go through every single map (at 4 voidstones) or swap to a different tab, move cursor to your inventory and right joystick over to quickly take a map.

Being able to quickly grab maps like others with a m+kb setup can would greatly enhance the flow of grabbing maps and improve end game content for steam deck or console users.
