Patch 1.16

- Upgraded game to Unreal Engine 5.4
- Fixed problem that caused virtual texture pool to reset every few seconds, which in turn caused hickups in framerates.
- Level streaming still causes small drops in framerates occasionally, but the impack is minimal when game is installed on SSD.
- Simplified lighting solution all around to boost performance.
- HUD crosshair now changes shape to a circle when pointed to a interactable object.
- Simplified room puzzle at the very beginning of the game in order to make the start more user friendly.
