Support SPDX lite as input to the plugin

[goneall]

Proposal: Add configuration parameter to the plugin which points to an SPDX lite document.

The plugin would read in the SPDX lite data and merge it with any other plugin configuration parameters.

Propose the SPDX lite document take precedence on any conflicts.

This would allow the SPDX metadata to be separated out into a separate file for better maintainability.

It would also allow most of the SPDX document to be maintained in the source repo.

See the SPDX tools discussion on the SPDX document storage for more information.

This seems to be a good inclusion. I'll work on it. I had a query is there some Spdx Lite support in the Spdx Java Library or elsewhere ?

SPDX Lite should be a subset of the tag/value format and I believe it should processable using the existing library code. This should be verified, however - it has been a while since I've looked at the at the lite spec.
