Added comprehensive game compression with image, audio, and video support
Features:

• Image compression using native Android Bitmap APIs with WebP format (lossless/lossy)
• Audio compression using FFmpeg-Kit with Opus codec
• Video compression using FFmpeg-Kit with h264_mediacodec (hardware acceleration)
• Compression settings dialog with quality controls for all media types
• Support for transparent images (RGBA preserved in WebP)

Bug Fixes:

• Fixed batch extraction/creation progress counter not updating during operation
  • Modified Python rpa_wrapper.py to accept and preserve batch information
  • Updated MainViewModel to pass batch info (index, total, filename) to Python
  • Python now includes batch info in all progress updates
  • ProgressViewModel simplified to read batch index directly from ProgressData
