improved logging, updated man pages, bug fixes

This release is some minor bug fixes, improved logging and updated man pages. Additional testing and development is needed on doi2rdm for the CrossRef crosswalk. Add ".cl_annotations" to track custom Caltech Library fields exported from EPrints. This will eventually be removed as the Invenio RDM data model improves (e.g. Invenio RDM 12 should include more of the journal fields we need).

The current release requires the latest versions of crossrefapi, eprinttools, and simplified Caltech Library Go packages.
