Include workflow provenance from resource maps

[amoeba]

Workflow provenance information contained in resource maps is currently not included when packages are triplified. The structure should have a nearly 1:1 mapping between the resource map and schema.org/SOSO so adding this in shouldn't be a big job. See the reference at https://github.com/ESIPFed/science-on-schema.org/blob/master/guides/Dataset.md#indicating-a-software-workflow-or-processing-activity-provused-and-provwasgeneratedby for a description of the structure.
