Cool-chic 3.2: Go fast boiii ๐Ÿ”ฅ ๐ŸŽ๏ธ

This release corresponds to the paper Overfitted image coding at reduced complexity, Blard et al., EUSIPCO 24

Notable improvements:

  • Fast CPU-only decoder
    • Decode a 512x768 image in 100 ms
    • C API for binary arithmetic coding
  • Encoding time reduced by 35%
  • Rate reduction of 5% compared to Cool-chic 3.1
