Consider refactoring schema to use additionalProperties: false

Consider refactoring your schema to use additionalProperties: false which entails flattening the $refs as suggested in networknt/json-schema-validator#1216 (comment)

I don't think we can implement the other suggestion of implementing line delimited JSON since the file format is constrained by the spec - perhaps we could pick up this possibility in the SPDX spec discussions.

Flatten $refs to use additionalProperties instead of unevaluatedProperties could lead to a huge schema, but may worth if the use case loads the schema once and validate multiple documents.

Could be implemented as an option (--use-additional-properties)?

PR #117 is proposed to implement the additionalProperties.
