Add feature or workflow to produce both inferred and non-inferred GPADs

[kltm]

Currently, the minerva processes in place only produce GPAD files with inferred annotations included. From a discussion related to SGD imports (geneontology/project-management#34), it would be good to be able to compare what annotation is being added to GPAD output from minerva.

Closing this ticket would be a documented CLI method (or series of CLI commands) of providing a set of TTL files (directory) and producing an inferred GPAD output file and an uninferred GPAD output file.

From meeting this morning, bumping implementation back to discussion.
