Code deprecated at Python3.10

[santimontiel]

Good morning everyone,

I am trying to run code from vod-tudelft library and it seems that some numpy features you are using are now deprecated.

File "/home/robesafe/.local/lib/python3.10/site-packages/vod/frame/transformations.py", line 379, in project_pcl_to_image
    uvs = project_3d_to_2d(points=radar_points_camera_frame,
  File "/home/robesafe/.local/lib/python3.10/site-packages/vod/frame/transformations.py", line 325, in project_3d_to_2d
    uvs = np.round(uvs).astype(np.int)
  File "/home/robesafe/.local/lib/python3.10/site-packages/numpy/__init__.py", line 305, in __getattr__
    raise AttributeError(__former_attrs__[attr])
AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'inf'?

I say this just to inform you, I could prepare a PR during the next upcoming weeks.

Bests,
Santi
