[BUG] Numpy types are deprecated

[tms-gvd]

Describe the bug Deprecated numpy types after moving to v1.0.1

Steps to Reproduce

• What version of the code were you using? Tell us the output of git log -n 1 ''' commit aa22d4d1d4cb30de12f6aac453e6f49b87b787db (HEAD -> main, origin/main, origin/HEAD) Author: Lahav Lipson llipson@princeton.edu Date: Mon Jul 3 01:22:06 2023 -0400 ... '''

• What command did you run?

  $BLENDER -noaudio --background --python generate.py -- --seed 0 --task coarse -g desert simple --output_folder outputs/helloworld/coarse

• What are your output logs?

  AttributeError: module 'numpy' has no attribute 'bool'.
  `np.bool` was a deprecated alias for the builtin `bool`. To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here.
  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: 'bool_'?

Fixed by replacing `np.bool` by `bool` at https://github.com/princeton-vl/infinigen/blob/aa22d4d1d4cb30de12f6aac453e6f49b87b787db/worldgen/terrain/utils/kernelizer_util.py#L78
Yet, another AttributeError is then raised:

** (If this is your first time running Infinigen) What are the full output logs of `install.sh` ?**
Running with Docker container, the errors are raised independently of the config (CUDA, OpenGL)

**Platform**
- OS & OS Version: Ubuntu 22.04.2 LTS 
- GPU (?) : NVIDIA TITAN RTX
- GPU Driver Version (?) : 530.30.02
- RAM (GB): 64

**Additional context**
It might come from the changes in `requirements.txt` of commit aa22d4d1d4cb30de12f6aac453e6f49b87b787db

Hello, it seems you are correct, this change slipped through but did not work on all platforms. Thankyou for catching it, please pull main and I hope this resolves your issue.

[tms-gvd]

Thanks for the fix. FYI, I have now a new line in the logs, at each step of the helloworld tutorial (running inside a docker container with opengl and no gpu). Yet, I get the expected outputs when generating GT with OpenGL

COULD NOT LOAD RichDEM ENGINE! NOTHING WILL WORK!
