PointMambaMix.forward() is an identity function

Hi authors, thanks for your work. I am confused about why PointMambaMix.forward() is an identity function in your implementation forward. The current version of the code is actually not a mamba-based network.

Thank you very much for pointing out a rather important bug, actually going through the previous forward_feature part, maybe because I accidentally deleted it while sorting out the code, thank you very much! I have corrected it,
