Added new namespace `Misaki.HighPerformance.Image` for image processing, including classes for animated GIF handling and memory management. Added `AnimatedFrameResult` class for individual frames in animated images. Added `AnimatedGifEnumerator` class for enumerating frames in animated GIFs. Added `ColorComponents` enum for different color formats. Added `ImageInfo` struct for image dimensions and color components. Added `CRuntime` class for low-level memory management functions. Added `MemoryStats` class to track memory allocation statistics. Added utility functions for creating multi-dimensional arrays. Added new structures for fixed-size UTF-8 encoded strings. Added benchmarking classes to test new memory management features. Changed `StbImage.cs` to include new namespaces and functionality for image data manipulation. Changed project files to target .NET 9.0 and enable new features. Changed `Arena.cs` and `DynamicArena.cs` to use `nuint` for size parameters. Changed `BitSet.cs` to enhance bit manipulation methods. Changed `Program.cs` to run `FunctionPtrBenchmark` for performance testing. Removed memory tracking code from `AllocationManager.cs`, including the `_allocated` dictionary and related logic. Removed `Free` method from `IAllocator.cs` interface. Removed `UNSAFE_COLLECTION_CHECK` preprocessor directive from the codebase. Refactored various files to improve organization, moving from `Unsafe` to `LowLevel` namespace. Refactored `MemoryUtilities` class to include new memory operation methods. Refactored `UnsafeUtilities.cs` to support new collection structures.
