1. Auto-detection now uses rglob to find TGA files in ALL subfolders
- Properly finds icons in version subfolders like 19.3.2.201024
- Shows relative paths in the file list
2. Default settings changed:
- Default canvas: 320x320 (index 5)
- Default upscale: No Upscaling (first in list)
3. Added iconcache.dat parser module (icon_cache_parser.py)
- Attempts to extract item names from binary cache file
- Uses heuristics to find icon ID to name mappings
