New decorators and effects

### Problem to solve

At the moment, the Flame library has a modest decorator system .

A powerful visual effects for the **Flame** game engine.
Pure dart 🎯

I want to add some new decorators to the flame library, which can be viewed at this link

### Proposal
Instead of fighting with complex WebGL Fragment Shaders that break on edge cases, fail to scale with Device Pixel Ratios, or ignore TexturePacker rotations.

## Features

- **`OutlineDecorator`**: Solid, strictly bound 8-way silhouette outline for pixel-perfect selections.
- **`PulseOutlineDecorator`**: A thick, smoothly pulsating outline that dynamically generates structural copies to eliminate tracing gaps.
- **`NeonGlowDecorator`**: A soft, cyber-punk glowing aura shadow utilizing dynamic `MaskFilter.blur` expanding rings.
- **`GhostTrailDecorator`**: Renders trailing, fading afterimages following your component to simulate teleportation or supersonic movement.
- **`HologramDecorator`**: Chromatic Aberration RGB-splitting offset glitch filter with randomized vertical jump jitter.
- **`DissolveDecorator`**: A teleportation/disintegration wave that mathematically erases the character using procedural noise grids and `BlendMode.dstOut`.
- **`HueDecorator`**: Hue shifting decorator
Which of these decorators are worth adding to the flame library?
