Improve the logic of 'cvp', now it provably works in all cases. Add 'reduced' option to 'linalg.lll.voronoi', this eliminates superfluous Voronoi vectors that do not have a corresponding face of the Voronoi cell, or this face would be smaller than 'rtol'. Simplify 'lattice.Polyatomic.neighbors' by providing the option to group equidistant vectors 'group_by_length' in 'linalg.lll.cvp'. See !165 for details. Closes #163.
