Reformat Amazon C4 dataset

[botka1998]

We want to pull additional data for each entry in the C4 dataset:

• main_category
• title
• features
• description
• images
• categories
• details
• parent_asin

We will grab each entry from the OG dataset ->
use the parent_asin2category to find the file containing the item and add the additional data to the dataset entry.
