Problem with pykdtree on Mac OS ARM

[maxmen]

On a Mac with ARM M3 processor, QuickView gets stuck, likely because of an issue with pykdtree. My solution was editing Particles.py and making the following changes:

• add:
  from scipy.spatial import cKDTree

• substitute:
  def __make_kdtree(self, pos):
  return KDTree(pos)
  with
  def __make_kdtree(self, pos):
  return cKDTree(pos)
