Adds Pheno4D point cloud segmentation dataset

First point cloud dataset added to AgML. Live on Hugging Face: https://huggingface.co/datasets/Project-AgML/pheno4d_point_cloud_segmentation (126 labeled scans, maize + tomato).

What's in this PR

  • New entry in static/data/hf_datasets.json
  • A sample preview image (3D scatter plot colored by segmentation label, generated from real data, since standard image-based sample rendering doesn't apply here)

Note on loader compatibility

This dataset's mask/mask_2 columns are Array2D (variable-length numeric arrays), not the Image() type HuggingFaceDataLoader currently expects for segmentation. So while this entry renders correctly on the site (using the closest valid enum values: machine_learning_task: semantic_segmentation, annotation_format: segmentationMask), the dataset likely won't load correctly through the existing loader without changes there. So it would need a new loader path.
