Photon Frame Generation

NEW
- AMD FSR 1 upscaling: the world and shader pack render at a lower resolution, then EASU upscales and RCAS sharpens it. HUD and menus stay at full resolution. Presets: Ultra Quality (77%), Quality (67%), Balanced (59%), Performance (50%), Ultra Performance (33%), Native + sharpen. Adjustable sharpness and texture LOD bias.
- Low Latency mode (Off / On / Ultra): reduces input lag while frame generation is active.
- Simple FPS counter: the overlay (F7) now has 3 modes: Off / FPS counter / Full diagnostics. The counter shows displayed, real, average and minimum FPS. Corner and offset are adjustable (e.g. next to Chloride's FPS counter).
- New option "Status messages" (off by default): automatic messages like "paused 5 s: generation costs ..." no longer appear on screen.

FIXES
- HUDs from other mods (Xaero's Minimap, Chloride FPS meter, etc.) no longer move or distort with the camera.
- Compatibility with QDAA: no more flickering.
- Less smearing during fast camera turns: generation pauses briefly when the image moves too far between real frames.
- Frame generation no longer turns itself off permanently when it's too expensive; it pauses for 5 s and tries again.
- Fixed entities and particles being drawn in the wrong place with FSR enabled.
