Subject: feat: Enhance model and texture loading with improved error handling
 and new features

- Introduced `LoadedModel` and `LoadedTexture` structs for better encapsulation of model and texture data.
- Added functions to load models and textures from archives, including support for resolving textures based on materials and wear entries.
- Implemented error handling for missing textures, materials, and wear entries.
- Updated the rendering pipeline to support texture loading and binding, including command-line arguments for texture customization.
- Enhanced the `texm` crate with new decoding capabilities for various pixel formats, including indexed textures.
- Added tests for texture decoding and loading to ensure reliability and correctness.
- Updated documentation to reflect changes in the material and texture resolution process.
