- Introduced `decodePixel` method in `VgaImage` to handle pixel mapping for planar VGA images.
- Updated `AsciiRasterizer`, `SixelRasterizer`, and `SoftwareRasterizer` to utilize the new `decodePixel` method for improved clarity and reduced code duplication.
- Centralized HUD drawing logic in the `Rasterizer` base class with `drawStandardVgaHud` method, allowing subclasses to easily implement HUD rendering.
- Removed redundant HUD drawing methods from individual rasterizers, streamlining the codebase.
- Enhanced documentation for clarity on methods and their purposes.
