  Update encoder:
   * booleanification
   * integer BR scores, may improve performance if FPU is slow
   * condense speed-quality constants in quality.h
   * code massage to calm down CoverityScan
   * hashers refactoring
   * new hasher - improved speed, compression and reduced memory usage for q:5-9 w:10-16
   * reduced static recources -> binary size
