TL;DR New features and improved everything

Features

I have fully reworked the grain sampling to be more accurate, more random and less repetitive. (Grain plate images are tiled with random offsets, position offset is now truly random)
Grain colour parameter was counterintuitive and messes with saturation so it has been removed
The grain intensity paramter functions more realistically. (The image is now always a result of the grain plate rather than lerping back to the original viewport image when intensity is a lower value, more true to how it works in real life)
There are new features! Lens distortion, customizable chromatic abberation, Radial blur, vignette repositioning, adjustable film border size.
Halation effect is fully reworked and much higher quality. Previously the halation didn’t show much outside hotspots and now it spreads to outside bright parts and looks more realistic.
Backend has been organized and cleaned.
