This commit introduces a new Python script, `terrain_map_doc_validator.py`, which validates terrain and map documentation assumptions against actual game data. The validator checks for the presence and correctness of various data chunks in the `Land.msh` and `Land.map` files, reporting any issues found during the validation process. It also generates a summary report of the validation results, including counts of errors and warnings, and statistics related to the map and mesh data.
- Implemented msh_export_obj.py for exporting NGI MSH geometry to Wavefront OBJ format, including model selection and geometry extraction.
- Added msh_preview_renderer.py for rendering NGI MSH models to binary PPM images, featuring a primitive software renderer with customizable parameters.
- Both tools utilize the same NRes parsing logic and provide command-line interfaces for listing models and exporting or rendering geometry.
- Updated .gitignore to include common Python artifacts and project-specific files.
- Added `archive_roundtrip_validator.py` script for validating NRes and RsLi formats against real game data.
- Created README.md for the tools directory, detailing usage and supported signatures.
- Enhanced nres.md with practical nuances and empirical checks for game data.
