1. Added client config options for camera for frame stacking 2. Created Stacked Screenshot Capture task, responsible for capturing screenshots and accumulating them 3. Changed Camera Capture template to work with stacked screenshots.

Summary
Adds optional frame stacking to simulate real long-exposure photography. When enabled, the camera captures multiple frames across the shutter duration and accumulates them, creating motion blur for moving subjects and proper light accumulation.
Motivation
Currently, changing shutter speed only adjusts brightness via gamma correction. Real long-exposure photography collects light over time, creating motion blur when subjects move during the exposure. This PR adds that simulation.
Related to issue #86 (motion blur suggestion).
Implementation Details
Core Changes
StackedScreenshotCaptureTask.java- Captures N frames across shutter durationCameraCaptureTemplate.java- Uses stacked capture if enabledmodifyGammais skipped to prevent double-brighteningConfiguration (Client-side)
Added to
Config.Client:USE_FRAME_STACKINGfalseScreenshots
Before (Current Behavior)
1", moving while shooting - no blur
1", standing in place
After (With Frame Stacking)
1" shutter, same movement - visible motion blur
1", standing in place, almost the same image
