There are a couple of fields that feel like they should be renamed to better represent what they contain:

• artifacts -> packages: the original idea is that this field would be a mix of all nodes in the SBOM graph, however, it's been way more practical to break out files into its own section, and there are no other types.
• artifactRelationships -> relationships: given the last point, this just represents relationships between any two nodes, so we don't need artifacts in the name
