Variation Dataset Generation from Raw Data

[suyashtambe]

The current process_variation_data.py script expects voxel graph data in a variation dataset, but no such dataset exists.
Currently, we only have:

Raw Data (.json) in 6types-raw_data/raw-data/

Processed Data (.pt) in 6types-processed_data/
Error: Voxel graph file not found: ./variation_test\7\voxel_data\voxel_000000.json
Generating 10 variations from Data 998...
Error: Voxel graph file not found: ./variation_test\4\voxel_data\voxel_000000.json

Since voxel data is only present in the raw dataset, we need to generate the variation dataset using transformations on raw data.
