TGA Icon Converter Improvements

AI Upscaling with Real-ESRGAN

• Added modules/ai_upscaler.py - Real-ESRGAN integration for AI-powered upscaling
• Designed specifically for low-res game textures/icons (not pixel art)
• 4x upscale factor with neural network enhancement
• Falls back gracefully if model not available
• Only shown in UI if Real-ESRGAN is installed

No Upscaling Option

• Added "❌ No Upscaling" as the default option
• Keeps original icon size, just centers on canvas
• Useful when you want the icon at original resolution on a larger canvas

Auto-Detection Fixes

• Changed from glob to rglob to search ALL subfolders recursively
• Now properly finds TGA files in version subfolders like 19.3.2.201024
• Shows relative paths in the file list

Icon Cache Parser

• Created modules/icon_cache_parser.py to parse iconcache.dat
• Attempts to extract item names from the binary cache file
• Uses heuristics: pattern matching for icon IDs, string extraction for names
• Challenge: proprietary binary format with no public documentation

Context

User clarified that game icons are "not pixel icons really, just quite low res" - Real-ESRGAN is perfect for this use case (designed for rendered graphics, not pixel art).
