  * FastLZ implementation of detour tile cache tile compressor.
  * You can define a custom implementation if you wish to use
  * a different compression algorithm for compressing your
  * detour heightfield tiles.
  * The result of compression runs is the data that detourTileCache
  * stores in memory (or can save out to disk).
  * The compressed heightfield tiles are stored in ram as they allow
  * to quickly generate a navmesh tile, possibly with obstacles added
  * to them, without the need for a full rebuild.
