vvenc-1.11.0-rc1

• finalized inter-frame parallelization (previously FPP)
• added vectorized DQ implementation
• improved SCC detection by reducing false positives
• added an affine speedup based on Pejman et al., ICIP 2023.
• overall speedups:
  • 6% for fast/slow/slower
  • 12% for medium, 25%+ for multi-threaded execution with long intra periods

vvenc-1.10.0

• first IDR per default at POC31 instead of POC0 to align with other GOPs
• improved RC, especially for high rates and low activity scenes, especially for HDR
• enabled spatial sub-sampling for 2pRC in preset faster
• number of MCTF references adaptively increased
• reduced the efficiency gap for dependent frame parallelism (still experimental, as not harmonized with RC)
• around 0.5% BDR gains for all presets
• many other minor cleanups and changes
