feat(kpoints): add time symmetry reduction with correct weights
Implement time-reversal symmetry reduction for k-points with proper weight calculation. Handles TRIM points (weight=1) and regular points (weight=2) correctly.
我这里只是加了一个修正后的考虑时间反演的函数。并没有用在 kmesh_sampling_negf中,因为我不在确定你这个kmesh_sampling_negf是否有额外的需求。你来看看评估一下 @AsymmetryChou
