v0.2.0

• Discarded BallTree and KDTree which are now replaced by a RTree: as fast and hyperparameter-free
  -> lsnms.nms is now twice faster to compile (only one tree to compile)
• cutoff_distance and tree are now deprecated. Warnings are issued when those are specified.
• cleared the tests structure
• added types conversion and sanity checks for data shape, etc
• cached all the jitted function which could (the non recursive ones) -> saves 2 seconds of compilation time at first use.
  -> lsnms.nms is now hyperparameter free, runs just as fast as before, and almost three times faster to compile at first use.
