Starting tracking causes this runtime error:

Traceback (most recent call last):
  File "C:\Users\e.kerkhof\.conda\envs\test_ndi\lib\site-packages\sksurgerycore\baseclasses\tracker.py", line 116, in add_frame_to_buffer
    my_index = self.port_handles.index(port_handle)
ValueError: 10 is not in list

During handling of the above exception, another exception occurred:

    raise AttributeError(
AttributeError: `np.NaN` was removed in the NumPy 2.0 release. Use `np.nan` instead.. Did you mean: 'nan'?

My assumtion is that in order for this to work again track_smoothing.py needs to be updated. Will create pull request.
